Bought this to carry a Bb shepherd's crook cornet and assortment of mutes: contrary to what manufacturers say, most cases with 'ample space for mutes' don't actually have that space. This case easily accommodates the cornet, together with straight, bucket, cup, harmon and wa-wa mutes. All stored safely and without risk of damage from striking other things within the case, thanks to the very extensive set of dividers and pads. Bought with the backpack strap accessory which also is easy to fit and comfortable. Overall case is light in feel when being carried and is easier to carry (in my opinion) than the top-entry triple case which it replaces.
In terms of strength, it isn't a flight case, but it will stand up to the general day-to-day job of transporting the instrument to rehearsals and concert in the car so it suits my needs very well.
Excellent service from Thomann: never dealt with them before but price was the best around. Case was out of stock wen ordered but delivered to me before the 'expected in stock' date shown at time of order. Well done.
