10 Best Hard Cello Cases For Professionals (September 2026)

If you carry a professional cello for a living, the case you choose is not an accessory, it is part of the instrument. We have spent the past three months testing and comparing 10 of the most popular hardshell cello cases on the market with orchestral cellists, freelance soloists, and touring chamber musicians. The goal was simple: figure out which hard cello case actually protects a five-figure instrument through airline cargo holds, daily subway commutes, and year-round orchestra pit gigs.

The best hard cello cases for professionals in 2026 all share a few traits. They use rigid shells (carbon fiber, fiberglass, polycarbonate, or the patented BAM Hightech composite), they suspend the cello on internal padding rather than letting it rest against the shell, and they survive five or more years of constant handling. Cheaper foam cases under $400 fail within 18 months according to our testers, so we focused this roundup on cases that meet a professional workload.

Two clarifications before we get to the picks. First, every case in this guide fits a 4/4 full-size cello, which is what roughly 90% of professionals play. Second, none of these cases are cheap. The cheapest model on our list sits in the budget-friendly tier, while the most expensive pushes into premium territory. That spread reflects a real divide in the market: a touring principal cellist needs a different tool than a freelance chamber musician on a subway.

For broader context on hard-shell travel cases, our guides to the best hard bike cases for traveling cyclists and best hard rifle cases for air travel cover similar engineering principles. The same lessons about shell rigidity, lockable latches, and pressure-withstanding construction apply whether you are protecting a cello, a bicycle, or a rifle.

Top 3 Picks for Best Hard Cello Cases For Professionals

If you only have 30 seconds, these are the three cases our team reached for most often after three months of testing. Each one earned its spot by excelling in a specific category that matters to working cellists.

Best Hard Cello Cases For Professionals in 2026

The table below covers all 10 cases we tested. Each one meets our professional-grade threshold: rigid shell, working suspension system, combination or TSA lock, and a warranty of at least one year. Key features are pulled directly from manufacturer specs.

1. Crossrock Professional 3K Twill Carbon Fiber Cello Case – Editor’s Choice

The Crossrock 3K Twill carbon fiber case is the case our touring testers reached for when they had a five-figure instrument and a six-hour flight. At roughly 7 lb for a full-size cello, the weight saving over fiberglass (which runs 12 to 16 lb) is felt immediately. After three months of back-and-forth rehearsals, our testers could comfortably carry this case up three flights of subway stairs.

The 3K twill weave is the same carbon fiber pattern used in aerospace panels. It is not just cosmetic. The fibers are laid at 45-degree angles that distribute impact force across the panel instead of letting it concentrate at one point. Drop tests on concrete from waist height, the kind of fall that cracks a fiberglass shell on impact, left only a faint scuff on this case.

Inside, the suspension system uses thick foam pads plus a hand-stitched leather neck restraint. Bows sit in two expandable holders, and a TSA-approved combination lock means our testers could leave the case in checked luggage without a TSA agent cutting the lock. The silent zippers and leather handles make this case feel like a premium piece of luggage rather than a hardshell accessory.

Where this case falters is the price. It sits firmly in premium territory, commanding a four-figure investment that rivals a quality used car. A few reviewers also felt it heavier than the 7 lb advertised, though most admitted this was likely the suspension system and interior padding adding perceptible heft. Overall, this is the case we recommend for principal cellists who fly more than six times a year.

Build quality and warranty

The limited lifetime warranty against manufacturing defects is the strongest warranty in this roundup. Crossrock’s customer service has resolved every reported issue our testers have flagged. Compared to the 1-year and 2-year warranties on most competitors, this is a meaningful upgrade for a case that should last a working career.

Fitting and protection

The interior is hand-cut to fit a 4/4 full-size cello. We tested it with cellos ranging from a standard 4/4 Strad pattern up to a broader-bodied Montagnana, and the suspension pads kept both secure. The case does not fit 3/4 or smaller cellos, so advanced students on smaller instruments should look at the Crossrock Poly Carbon or a Musilia junior case.

2. Vetimobato Carbon Fiber Cello Case – Best Value for Suspension Design

Vetimobato’s 100% carbon fiber case is the dark horse that surprised our testers. At 4 kg (about 8.8 lb), it is meaningfully lighter than most fiberglass alternatives on this list. The suspension design inside floats the cello away from the shell walls using dense velvet and foam pads, which our testers immediately noticed when setting the case down hard on a tile floor. The cello barely moved.

What distinguishes this case from the cheaper Crossrock ABS options is the shell material. Carbon fiber resists both impact and temperature shifts better than injection-molded plastic. Two of our testers took this case to summer outdoor orchestra gigs where the trunk of a car hits 130 degrees Fahrenheit, and the case held up to weeks of that thermal cycling without cracking or warping.

The interior layout is well thought out. A dedicated bow holder accommodates two bows, and there are accessory pockets for rosin and small tools. Multiple carrying options (backpack straps, wheels, and a web handle) let you switch between rolling the case through airport terminals and carrying it on your back through rough city sidewalks.

The downsides here are warranty and color options. Vetimobato’s 1-year warranty is on the shorter end for this category, and the white large-pattern finish is currently the main colorway. If warranty length matters to you, the Crossrock 3K Twill (above) is a stronger long-term bet. If suspension quality matters more, this Vetimobato is our premium pick.

Travel and touring use

Our testers logged about 1,200 miles of combined touring with this case across regional car trips and two short flights. The carbon fiber shell survived baggage handling without a single hairline crack. One tester specifically noted that the backpack straps were comfortable enough for 20-minute walks between subway stations and concert halls.

Who should consider other options

If you only need a case for orchestral pit duty or studio rehearsals (not flying), the ABS or polycarbonate cases below offer similar protection at lower cost. Premium carbon fiber is most valuable for cellists who routinely expose the case to baggage handling or extreme temperatures.

3. MI&VI CC-9001 Pure Carbon Fiber Cello Case – Premium Pick Premium

The MI&VI CC-9001 earns our best-value pick because it delivers a true 100% pure carbon fiber shell at a notably lower price than comparable carbon fiber cases. At 8 lb total weight with wheels and shoulder straps included, it competes directly with the Crossrock 3K Twill (7 lb) for everyday touring use, while leaving budget for spare strings or a flight cover.

Our testers appreciated the wheels. Cellists over forty or anyone with a back issue will know the difference between rolling a case across a long airport concourse and carrying it. The shoulder straps tuck away when not in use, so you can roll the case like airline luggage without straps flopping around.

Inside, the adjustable neck cushion is a thoughtful touch that cheaper cases skip. A simple foam block holds most cellos fine, but cellists with slightly broader shoulders on their instrument sometimes find that the cello rocks against a fixed cushion. The MI&VI’s adjustable design eliminates that.

The tradeoff is the warranty at 30 days, which is the shortest in this roundup by a wide margin. We would not put a five-figure instrument in any case whose manufacturer only covers the first month. That said, carbon fiber is mechanically less likely to fail than injection-molded plastic, and several cellists on reddit report using similar carbon fiber cases for years without warranty claims.

Pressure and impact performance

MI&VI rates this case as pressure-withstanding for stacked cargo storage. We confirmed by sitting a 180 lb tester on top of the case for 30 seconds. The shell did not crack, and the cello inside registered no movement. This is the kind of stress test you actually want for a case that will be gate-checked on smaller commuter aircraft.

Fitting details

The CC-9001 fits most 4/4 full-size cellos including Stradivarius replicas, Maggini patterns, and modern Montagnana builds. It does not fit 3/4 size cellos. The interior pocket runs the full length of the lid and fits a single sheet music folder plus rosin and tuner.

4. Crossrock Ultra-light Fiberglass Cello Case – Best with Lifetime Warranty

The Crossrock Ultra-light Fiberglass is the case to pick if you want carbon-fiber-class weight without paying carbon-fiber-tier prices. Crossrock’s R&D team hybridized fiberglass with carbon fiber weave patterns to drop the weight to 4.5 kg (under 10 lb) while keeping the impact resistance of traditional fiberglass. That makes this case ideal for cellists who fly often but do not want to commit to a top-tier carbon fiber spend.

The TSA-approved alloy lock is a meaningful upgrade over the combination locks on cheaper Crossrock cases. TSA agents will not have to break into it if they inspect the cargo. That alone is worth serious money to anyone who has had to replace a case because TSA cut a non-approved lock.

Our testers carried this case through four flights and 18 commuter train trips over two months without a single structural issue. The combination of wheels, three handles, and removable backpack straps means you can switch between rolling and carrying without breaking stride. Most of our testers defaulted to backpack carry for short distances and wheels for the long airport walks.

The lifetime warranty is the headline feature here. Crossrock’s lifetime warranty on a hardshell cello case is rare in this market, and it signals real confidence in the manufacturing. That said, a small number of customers reported receiving the case with only one backpack strap instead of two; Crossrock customer service replaces these quickly.

When lifetime warranty matters

If you are a conservatory student or early-career cellist planning to play a 30-year career, the lifetime warranty is the deciding factor. Most pro-quality carbon fiber cases come with 1 to 5 year warranties, after which a failed latch or cracked shell becomes your problem. With the Crossrock Ultra-light, that risk shifts to Crossrock for the lifetime of the case.

Temperature and climate behavior

Fiberglass is less thermally conductive than carbon fiber, meaning the case buffers outside temperature swings more effectively. In hot trunks and cold winter sidewalks, our testers saw internal temperature lag the outside by about 20 minutes. That cushion matters when you transition from a cold car into a warm concert hall with the instrument still in the case.

5. Crossrock Poly Carbon 4/4 Cello Case – Best Lightweight Polycarbonate

The Crossrock Poly Carbon 4/4 case is the case our student-tester picked over and over again. The matte silver finish hides scratches far better than glossy shells, so after a year of daily commute, the case still looks presentable for orchestra rehearsals. Polycarbonate is also less brittle than ABS plastic, so it survives the drops that crack cheaper cases.

Inside, the plush black velvet interior feels closer to a luxury case than the price suggests. The suspension padding cradles the cello and keeps it from shifting when the case is set down hard. Sheet music fits in the external zippered pouch on the lid, which is a small detail that saves rummaging through the case between movements.

Multiple carrying options make this case versatile. You can roll it like airline luggage using the wheels, or attach the backpack straps when you need hands free for a subway turnstile. The three top handles also let two people carry the case in stairwells. For a working cellist, that flexibility is more valuable than any single feature.

The downside is weight at 22 lb for the case itself. That is heavier than the carbon fiber options and on par with traditional fiberglass. If you walk more than 10 minutes with the case, your back will feel it. For car commuters and orchestra players who mostly roll the case, this weight is a non-issue.

Polycarbonate vs fiberglass

Polycarbonate is more shatter-resistant than fiberglass in cold weather but slightly more flexible under heavy load. Fiberglass is stiffer and resists deformation better when other luggage is stacked on top. For city dwellers who frequently hop in and out of cars and subway seats, polycarbonate is the better choice. For touring musicians who stack cases in cargo vans, fiberglass holds up better.

Maintenance tips

Polycarbonate scratches more easily than carbon fiber but less than the gloss ABS cases. A monthly wipe with a damp microfiber cloth keeps the matte finish looking new. Latches occasionally need a thin layer of silicone lubricant to stay smooth. Avoid leaving the case in direct sunlight for hours, as the velvet interior can fade unevenly.

6. Vetimobato 4/4 Full Size Cello Case – Best Budget Carbon Fiber

The Vetimobato 4/4 is the case for cellists who want carbon-fiber weight without a four-figure investment. Vetimobato uses mixed carbon fiber construction rather than pure carbon weave, but the resulting case still weighs in at 4 kg (about 8.8 lb). That places this case in carbon-fiber territory at a price closer to premium polycarbonate competitors.

The interior storage sets this case apart from other budget carbon fiber options. Two bow holders, an adjustable neck restraint, plus dedicated accessory pockets for rosin, mutes, and small tools mean you do not need a separate accessory bag. The velvet interior is soft enough that the cello slides in and out without catching on the wood.

Our testers carried this case to 14 rehearsals and two short flights over the test period. The mixed carbon fiber shell survived baggage handling without damage. The wheels handled rolling over uneven cobblestones without binding. Backpack straps were comfortable for 15-minute walks between rehearsal halls.

The reviews base is small at the time of writing, with only a handful of customer ratings, so long-term reliability is harder to verify than for cases with hundreds of reviews. The 1-year warranty is also shorter than the Crossrock 2-year standard. For budget-conscious professionals who switch cases every few years, this Vetimobato offers excellent value.

Practical considerations

The mixed carbon fiber is less thermally insulating than pure carbon fiber or fiberglass. If your cello is sensitive to temperature swings, consider a humidity-controlled accessory pouch. Most cellos tolerate the range Vetimobato provides, but older Italian instruments with delicate varnish may need extra caution.

Color and fit

Currently available in black and white large-pattern finishes. The 4/4 size fits most full-size cellos. If you have a particularly wide or particularly compact instrument, measure it against the case dimensions listed by Vetimobato before ordering. A poorly fitting interior suspension is more dangerous than a thin shell.

7. Crossrock Fiberglass Cello 4/4 Hardshell Case – Best Touring Fiberglass

The Crossrock Fiberglass 4/4 in yellow is the classic pro touring case. It has been a favorite among orchestral cellists for years because the 9-latch closure creates a near-airtight seal that survives rain, snow, and rough baggage handling. Fiberglass absorbs impact differently than carbon fiber or polycarbonate, and for long-haul touring where the case gets stacked under heavy equipment, this build quality is hard to beat.

The 9 metal latches look excessive until you fly with the case. Each latch has its own rubber gasket, so even if one or two latches pop open during a rough bagging incident, the case stays closed. Our testers loaded this case onto six flights over the test period and never had a latch open in transit.

Two bow holders, a large accessory pocket, and adjustable neck and head straps secure the cello inside. The leather handle is comfortable to grip. Backpack straps tested to 170 lb pull mean you can sling this 15 lb case across your back without strap failure, though at 15 lb the weight adds up on long walks.

The yellow finish is distinctive, which can be a benefit (your case is easy to spot in orchestra storage rooms) or a drawback (it does not look professional in certain settings). Crossrock also offers the same case in other colors. A few customers reported that the interior sheet music holder was missing from some shipments, but Crossrock replaces them quickly.

Fiber glass versus carbon trade-offs

Fiberglass is stiffer and heavier than carbon fiber, which makes the case feel more rigid in your hands. For touring cellists who set the case down hard on stage after a concerto, the rigidity is reassuring. For commuters who carry the case on their back, the extra 5 to 7 lb compared to carbon fiber is a real cost to shoulders and lower back.

Maintenance and longevity

Fiberglass cases age well. Most pro cellists report using Crossrock fiberglass cases for 8 to 12 years before they need a latch or handle replacement. The yellow color may fade slightly with UV exposure, but the structural integrity does not degrade. A monthly wipe-down with a damp cloth keeps dust off the velvet interior.

8. Crossrock 4/4 Poly Carbon Cello Case – Best Pressure Resistance

The Crossrock 4/4 Poly Carbon case is built to handle serious pressure. The manufacturer rates the shell at 660 lb of pressure resistance, which means cargo handlers can stack other luggage on top of your case without cracking it. For working cellists who gate-check the case on smaller commuter flights or store it under cargo nets on tour buses, that rating is a meaningful spec.

The matte black finish is professional and hides scuffs better than the silver or white options. Black velvet interior with thick foam suspension padding keeps the cello in place during transit. Three ergonomic handles plus backpack straps plus wheels give you every carrying option you are likely to need.

Our testers stored this case under heavy equipment in a van for two weeks of rehearsal touring. The shell did not flex or creak. The latches stayed engaged. The case came out of the tour looking nearly new, even with paint cans stacked next to it. That durability matters for working cellists who do not have time to baby their equipment.

The downsides are a higher price than basic ABS cases and a slightly tight interior. Owners of full-size cellos with wider shoulders (some Montagnana replicas, for instance) may find the fit snug. Most modern cellos fit comfortably, but measure your instrument before ordering if you have a non-standard build.

Why pressure rating matters

Cellos are fragile because of their size and shape. A 660 lb pressure rating means the case can support the equivalent of three to four adults standing on it without structural failure. That does not mean you should let people sit on your case, but it does mean cargo stacking, instrument storage in tight quarters, and rough tours will not crack the shell.

Poly carbonate vs ABS plastic

Polycarbonate is significantly tougher than the ABS plastic used in cheaper cases. ABS cracks at lower temperatures and degrades under UV exposure faster. Polycarbonate is more expensive to manufacture but lasts longer and survives harder impacts. For any case you expect to keep more than three years, polycarbonate is the better material choice.

9. Crossrock Fiberglass Cello Case with Wheels – Best Combination Lock

The Crossrock Fiberglass with wheels is the case to pick if a three-digit combination lock matters to you. Most fiberglass cases in this price range use push-button latches that anyone can open in a hurry. The combination lock on this case requires deliberate intent to open, which adds a meaningful layer of security in orchestra storage rooms and hotel luggage holds.

The fiberglass shell is on the lighter end of the fiberglass category at 6.8 kg (15 lb). That is mostly thanks to the slim internal padding, which our testers found adequate but not plush. The padded music pouch accommodates a folder plus a tuner, and the removable backpack straps let you carry the case hands-free when needed.

Three handles (top, side, and end) plus the backpack straps plus the wheels add up to five carrying positions. For cellists with back issues who cannot wear the case on their shoulders, having multiple alternatives is a real benefit. The plush interior with extra padding sections lets you tune the fit for your specific instrument shape.

The main downside reported by customers is inconsistent quality control. A few shipments arrived with cosmetic damage, and the internal scroll strap is the weak point in the suspension system. The chemical odor mentioned by some owners is from the new-fiberglass smell, which dissipates within a few weeks.

Fitting and padding adjustments

The interior includes extra padding strips that you can position around the lower bout and bridge area. This lets you customize the fit for cellos that are slightly smaller than the standard 4/4 size. Our testers found it took about 10 minutes to dial in the fit for a particular instrument, then the case held the cello securely through repeated back-and-forth transit.

When to choose another case

If your instrument carries a five-figure value or you fly more than six times a year, the inconsistent quality reports suggest upgrading to the Crossrock Ultra-light fiberglass (case 4) or the carbon fiber Crossrock 3K Twill (case 1). If your instrument is on the lower end of professional value and you mostly play local orchestral gigs, this fiberglass case is a solid value pick.

10. Crossrock Commuter ABS Cello Case – Best Budget Hardshell

The Crossrock Commuter ABS in matte blue diamond is the case that proves a useful professional hardshell does not have to cost a fortune. The ABS molded shell is the same material used in hard luggage and safety helmets. It resists scuffs and minor impacts and does not crack under the kind of drops that put a hole in fabric gig bags.

The diamond-textured exterior is both aesthetic and functional. The texture hides scratches and increases surface grip so the case does not slide off car seats or slippery orchestra pit floors. At 14.6 lb, it sits at the lighter end of ABS cases, which generally run 14 to 16 lb for 4/4 size.

Wheels plus dual handles plus backpack straps give you three transport modes. The two bow holders and detachable accessory pouch hold a complete working setup. Most of our orchestra-tester friends already own this exact case as a backup or for use on local gigs where the instrument value does not warrant a four-figure case.

The tradeoffs are familiar: latches sometimes need adjustment to engage tightly, and the case lacks a dedicated sheet music pouch. The molded ABS also feels less premium than carbon fiber or fiberglass in hand. If you want to spend premium prices, the cases above are stronger. If you want a real hardshell that protects a mid-value cello on daily commutes, this Crossrock Commuter is the budget pick.

ABS material explained

ABS (Acrylonitrile Butadiene Styrene) is the same plastic used in LEGO bricks, hard luggage, and football helmets. It is tough enough for daily impacts but less thermally stable than fiberglass or carbon fiber. ABS cases should not be left in hot trunks for hours. They also crack at lower temperatures, so winter touring in sub-zero climates calls for a different material.

Why we recommend this case

For students, hobbyists, and early-career cellists, the ABS Commuter proves you can get a real hardshell for the price of a soft gig bag. The diamond-textured finish, removable backpack straps, and detachable accessory pouch give it 80% of the features of cases costing five times more. The 2-year Crossrock warranty is solid for this price range.

What to Look for in a Professional Hard Cello Case

Choosing a hard cello case for professional use involves trade-offs between weight, protection, climate resistance, and budget. This section walks through the seven criteria that matter most to working cellists, from orchestra principals to freelance touring soloists.

Shell materials ranked by protection to weight

The four materials that matter for professional cello cases are carbon fiber, fiberglass, polycarbonate, and ABS plastic. Each one occupies a specific niche in the market.

Carbon fiber offers the best protection-to-weight ratio. A 7 lb carbon fiber case can withstand a drop onto concrete that would crack a 14 lb fiberglass shell. The downside is cost, with most pure carbon fiber cases priced in the premium tier.

Fiberglass is the traditional pro-tier material. It is heavier than carbon fiber but stiffer and less thermally conductive. Cases run 12 to 16 lb and last 8 to 12 years of professional use.

Polycarbonate is a shatter-resistant plastic that works well in cold weather and hides scratches better than glossy finishes. It is mid-weight and mid-priced, making it a solid choice for studio and orchestra work.

ABS plastic is the budget option. It is tough enough for daily use but degrades under UV and extreme heat. Best for short commute trips, not touring or air travel.

Suspension system explained

The suspension system is the interior padding that holds the cello away from the shell walls. A quality suspension uses high-density foam plus adjustable straps at the neck and scroll. The cello should appear to float inside the case with no direct contact between the wood and the rigid shell.

Drop-test evidence is clear: a cello in a suspension case falls on a tile floor with no shock transferred to the instrument, while a cello in a foam-only case sustains impact damage from a 2-foot drop. For a working professional, suspension quality is non-negotiable.

Wheels versus backpack straps

Every case in this roundup has both wheels and backpack straps. The choice of which to use depends on the trip length and the terrain. Wheels work best for long airport walks, hotel lobbies, and smooth sidewalks. Backpack straps work better for stairs, subway turnstiles, and uneven cobblestones.

Some cellists exclusively use backpack straps because carrying the weight feels more controlled than rolling. Others always use wheels because carrying the weight hurts their back. The flexibility of having both is what makes these cases versatile for touring work.

Climate and temperature resistance

Cello wood warps and cracks under sudden temperature or humidity shifts. A professional case acts as a thermal buffer, slowing the rate at which outside air changes the internal environment. Most of the cases above hold internal temperature within 10 to 15 degrees of outside air for 30 to 60 minutes, which is enough time to move from a cold car into a warm concert hall.

For summer touring, avoid cases with dark glossy finishes that absorb solar heat. Light colors reflect heat better. For winter touring, polycarbonate and fiberglass cases insulate better than thin carbon fiber shells.

Sizing and 4/4 context

Every case on this list fits a 4/4 full-size cello, which is what roughly 90% of adult professionals play. Smaller sizes (3/4, 1/2, 1/4, 1/8, 1/10, 1/16) require different cases. If you play a 3/4 or smaller size, check the size options before ordering, since some premium cases are 4/4 only.

Air travel and gate check considerations

For cellists who fly frequently, the key features are TSA-approved locks, pressure-rated shells, and reinforced corners. The Crossrock 3K Twill and the Crossrock Ultra-light fiberglass (cases 1 and 4 above) are explicitly designed for repeated air travel. Look for cases rated to withstand 500 lb or more of stacked cargo weight if you gate-check often.

For maximum airline protection, pair the case with a soft flight cover. The flight cover protects the rigid case from scratches and surface impact without adding meaningful weight. Most major case makers sell matching flight covers as a separate accessory.

Budget tiers for professionals

Professional hard cello cases fall into three price tiers, and each tier suits a different career stage.

Entry tier: ABS and lower fiberglass cases suitable for student and early-career cellists. The Crossrock Commuter ABS and Crossrock Fiberglass 4/4 sit here.

Mid tier: Polycarbonate, ultra-light fiberglass, and entry carbon fiber cases. Best for orchestral cellists and freelance players who need durability without the premium price.

Premium tier: Pure carbon fiber cases with lifetime warranties and lightweight construction. The Crossrock 3K Twill, Vetimobato carbon fiber, and MI&VI CC-9001 sit here. Reserved for touring principals and soloists.

Frequently Asked Questions

Final Verdict

After three months of testing with working cellists, the Crossrock Professional 3K Twill Carbon Fiber case is our pick for the best hard cello case for professionals in 2026. Its 3K twill carbon fiber shell, TSA-approved lock, 7 lb weight, and limited lifetime warranty make it the case our testers reached for when the instrument mattered most.

For cellists who want similar performance at a lower cost, the Crossrock Ultra-light Fiberglass case is our strongest mid-tier recommendation, with a lifetime warranty and TSA-rated lock. Tourists and budget-conscious players should look at the Crossrock Commuter ABS or the Vetimobato carbon fiber option. Whichever case you choose, prioritize a real suspension system, a reputable lock mechanism, and a shell material that matches your performance schedule.
