The mouse was immediately recognized in Windows 8.1 and do their duty quite reliable. Is 1x Previously happened that the mouse has very geruckelt, despite unchanged pad. There has helped mouse over the switch at the bottom off and on again.
The mouse goes into a kind of standby mode when no Bluetooth connection is more, but it also reports if no connection is established, in which the LED on the top is flashing rapidly. So you will not forget, perhaps the switch down and make out as to prolong a bit the life of the battery.
A small processing error I have criticized and indeed the right mouse button sometimes hangs when you press. So you realize that the resistance in comparison to the left button is higher and the clicking sound is noticeably louder than the left. But this is a deficiency with whom I can live quite well and did not cause me to return the mouse again.
Generally I find the mouse from the price / performance ratio very good and would bring me again, or friend.
