Touch is not bad in this range, we know that we are not dealing a "normal" piano but that's the joke. The configuration is simple to except to remember the key combination to adjust, which can be complicated for a lot of people.
The number one piano sound is convincing, thoroughly and eyes closed we will believe, but the other sounds are below, not really usable. The buttons respond well, but it is quite different from that of a real piano course games.
Bought for my girlfriend, it does the job. I think at that price, it's pretty flawless, that said this is not the digital piano rolls.
