At first glance, this mouse looks very well thought out. At first because by using it you quickly realize that it has a weak point. Her size. Not allowed for large hands. After more than an hour of use, appearance of pain in the fingers (ring finger and little finger) have to be pressed against the right side of the mouse. No feeling of comfort or hand may arise and rest. We are obliged to make a required effort. In short not at all suitable when it is used for both office and gaming. Beyond that it might be fine for someone with small hands and that is used for the desktop but on top of that there are connection failures and you have to refocus mouse pointer which causes many gestures for nothing. Note that I did all the updates on the Logitech site. Finally I returned for a mouse with Logitech M500 wireless. Bp over wireless links, and a big mouse for better grip.
