Not at all what you would expect! Be aware!
I saw this product a little time ago. Thought it could respond to my expectancies and even let it to my future children to study. But it is not at all what it is described. All you see is the image, not usability, nor quality keyboard.
It is just external design, but it is not that high quality, how Yamaha describes it.
It is a regular midi (even if they tell you its a digital piano). You can use it this way, but it has NO USB OUTPUT and no AC Adapter. You have to buy all that stuff above that $160 you pay for this "instrument". It is rather a toy, not an instrument you can play. And another big problem is that it has latency. When you plug midi ports (I bought ones) you would expect a delay in your DAW. So, be prepared for a latency of "a bit later after you press the key".
Of course it has its own sound, but it is too reverberated (not very quality reverb) and touch response it not very quality-like. You get 3 types of response (only): hard, silent and medium. This is not very useful for expression, but you have to decide for yourself.
I am very unsatisfied because of buying this and because of Yamaha's marketing. What is good at Yamaha is their Grand Piano, not digital, or other stuff.
