Coming back to see my former post as surprise on seeing me forgetting a small comment on my first trombone.
It's a 1988 model that I use since 1990 (bought used).
It is 2007 and I still play regularly (approx 1 hour per week).
That is, it took hold and in time.
The slide is nice but slightly less flexible than my bass.
It is by the cons too pushed in the volume because it tends to copper rather easily.
The patent has very good durability. The only trouble was the key that broke Barillé. But beautifully repaired by a gallery tours.
I had not tried before other model is my teacher that I had chosen (thank you Frank Fum .....)
I found the price was right then.
I reerais without hesitation because I had that choice and I had a wonderful time with.
