I play one. I really like it, the intonation is pretty good, flexable enough that I can adjust with minimal embouchure contortion. Sounds great with the Otto Link STM NY 7 mouthpiece I use.
The only negative really, and it probably could be addressed very quickly by a trip to the tech, is the feel of the G# key. It activates quickly and accurately, but feels numb and disconnected.
Very happy with my horn, and will be playing it on a paying gig this Saturday!
Good value.
