Bought this for my 8 years old daughter as a piano +.
I was amazed by the feel of the instrument, it's amazing sounds, and the ease of it's use (great interface). My daughter loves it and experiments with all those great options (and there are lots of them). The instrument sounds very professional and built very well. I can clearly say, this instrument can serve you for your entire life.
Kudos to Yamaha!
