The feel is horrible. Some have compared the feel to a touch notebook. This is totally false.
The feel is * worse * than a laptop. I already threw pc keyboards for less than that and the qwerty keyboard of my MacBook is much more accurate! Velocity is a feature-cons, because it depends on the angle at which you press the keys. Some keys do not engage the first time and that I read the robustness is random.
The manual is correct for a keyboard of this price.
I have since yesterday, I hesitate to return. If I had to try it, I would not have bought.
Touch is disastrous, and it is bad, I paid 20 € more to get a feel correct (I used toys to 10 € with a touch much better, just missing the south).
Useful only to play tablecloths or large agreements. Forget the rest. Actually, no, do not buy it
