When unpacking the mouse, I realized that the battery was leaking. Logitech should pay attention to the batteries included in its products. That's why I put only 3 stars. After having wiped the inside of the mouse and replace the battery, the product itself is fully consistent with the description and very pleasant to use. I have a mouse pad with a photo, glossy, on which none of my mice worked. Here, no problem. This also works on a varnished wood desk. By cons it does not work on the glass (which is normal and announced). Little more useful: the mouse has an on / off button to turn it off when not in use and thus extend the life of the battery.
