Allowed for the price and you can not complain really. If you want it but you could possibly say that the keys are very easy to press. In my it is the right mouse button. Initially öfterversehentlich depressed when I rested my fingers on it. But you get used to it.
The blue LEDs always remain on when the mouse is plugged in. Mag some nerves, I think it's a beautiful blue night lamp on the desk ;-)
