The middle mouse click is rather awkwardly positioned, which spoils the impression a bit. Nor is the degree of positive volume of mouse clicks you can have "bothersome for a quiet time" call.
Truly negative but then the driver. This does not allow such, typing on the touch surface is recognized as a click. A mouse can only be carried out by the (just loud) mechanical click switch.
In particular, if you just use the touch function, just feels do not sound at right and requires grasping (either because I hold the mouse as a normal mouse click or can I have the hand on the mouse like a touchpad and can not really click). As soon has her a driver update.
