I use the keyboard at home, playing from time to time as a hobby, composing some songs.
The keys are amazing, compared to similar keyboards with more techie features. This is the deal actually, with that one you don't have all the features that other models might have, but at least you have decent keys to play. It's not close to piano keys, but the feelings is very nice.
I don't have any negative to say. People might say that you need to spend some time to program it as a negative thing. Well, in my case I don't need that much of a hacks. I just need to plug and play. Easy stuff like volume, velocity etc are super easy to be adjusted, so for normal use it's 100% perfect.
