Beautiful, pleasant to touch and perfectly functional

Pretty and pleasant in the hand, this mouse works perfectly on all media including sweater or on the hand when one is far from a support. It's perfect for small hands and my wife uses it a lot and with pleasure. The life of the battery, suitable for over a year, could not be tested, my purchase dated less than a month, but in comparison, the battery of the mouse Microsoft Wireless Mobile Mouse 4000 comparable to the mouse and Logitech purchased shortly afterwards has to be replaced, while the frequency of use is identical.
