I bought this mouse to link it to a laptop. She was immediately recognized by Windows 7 and its installation took only a few seconds Among its points we note the size of the connector which is really very little that can store the laptop in his bag without disconnecting or storing connector into the slot for this purpose under the mouse which avoids losing it. Its weak point is the switch placed under the mouse, the handling is not easy and it is common to forget (minor fault is corrected with time) In conclusion I am very sastisfait this purchase
