Great for practising finger work on a sax, and also for just having fun. Its lightweight, Slightly difficult getting used to playing with 3 cables connected to it. I connected it to my phone and headphones to use with iReal and it's perfect. My only complaint is there is no case or bag to keep it in and no stand you can purchase, seems a pity that Yamaha think just laying it flat on a table collecting dust when not being used is ok. I expected a case to be part of the deal but not so. No spare O rings , USB cable or batteries included in the box. Despite my complaints I like it a lot. I wasn't too happy with the packaging of everything I ordered. Reeds and mouth pieces left loose in the box. Would have been better to wrap these items in some bubble wrap bag and nestle in between items, not on the top of the box all loose. I had ordered an alto and soprano and the Yamaha yds120. All came in one box via international shipping with no padding between saxophones boxes and cardboard shipping box. Should have been a bigger box with all 3 saxophones sitting inside a padded shell. No damage despite the flimsy packaging, but one sharp dig on the outer box would have definitely done major damage to one of the saxes.
