After 2 years of daily use, one of the two handles needs a little stitching, but I was putting in the case the trombone, a microphone, a mute, lubricants, a laptop, and my headphones. It is really big, and very good quality.
I overdid it.
I believe it's the best choice if you have to carry more than just the trombone. Not good if you need a small case.
