This bass trombone is good for the price. It might have an issue or two (one of my trigger slides moves a little too easily), but from my experience, when you buy these Chinese instruments, you generally should prepare for a visit to the repair shop right away. I took off a star because mine arrived with a slightly bent bell.

Fantastic instrument. Came right out of the box working great. Rotors needed just a bit of oil, but all slides move well. Would recommend for anyone looking for a solid doubler instrument
