Perfectly recognized by Windows XP and Seven, installs easily just by plugging the USB mini clip, the more it comes with a battery, a rarity these days! So good I bought 4 (2 for 2 at home and at work). This wireless mouse is light and precise, slightly lower than a basic wired mouse size is not too small either and does not generate fatigue in the hand or handle. The optical diode emits no visible light to the eye human, as under the mouse is removed the cover to access the battery, a small space is reserved for storing the mini USB clip, it is convenient not to lose as we takes the mouse in a laptop bag or to move to another PC. I recommend this purchase, as always, the price and delivery is impeccable at Amazon.
