I use it for three months, I also have a money jar Jupiter.
The Yana appears well above Jupiter's quality and loudness.
The color of sound and playability are the strengths of the saxophone.
I also tried a Yamaha high-end, the sound seems a little more "static": although very accurate, the Yana is much easier to modulate.
Value for the right price (3290 euros in Woodbrass, service + +)
Finish good, Color "Copper" in contrast with the brass keys very nice.
