First of all the quality of the build is good, and the case and accessories are great. But the usability of the keys for the left hand side, played by the little pink finger , is totally terrible by design and ergonomics. I have never seen such a design that was so bad. I was not able to play it properly with my hands. Even compared to my baritone, and tenor saxophone the distance is crazy big. So after two days if testing, I concluded to send back. Besides this dealbreaker of the keys the sound was reasonable but not great and the lower keys were not airtight.
For new customers I strongly suggest to find another more playable sax.
