This mouse works on almost all surfaces, except for glass, marble and carpet. It is of normal size.
Too bad the USB device is not black ... and a little smaller ...
/! \ It is necessary by connecting the USB device against before turning on the computer or the mouse wheel is extremely sensitive and you must restart your computer for comfortable use (even for the first use)
Who used to use the mouse with both hands, the Arc Mouse hurt my hands for 1 or 2 days. Now that I got used to it I am very pleased.
It is convenient, easy rengeable by its power retractable (Fold, she goes off). In addition, it comes with its protective carrying pouch.
On batteries, these are 2 AAA (small) lasting +/- 6 months. The mouse goes to sleep automatically. A small green LED lights up when the mouse unfolds and turns off soon after. It turns red when the batteries are drained.
It is provided with a button on the left side practice, but that we forget because it is located too far forward. This button is preset to "Previous Page" but it is adjustable by the Microsoft IntelliPoint software, which installs automatically with the mouse connection (need still an internet connection for installation I think).
The black surface of the top of the mouse is called "peach skin" leaves traces of the fingers (sebum and moistness) but is (near) scratchproof!
Its original price is expensive (50), but the quality / price is respected (currently less expensive - I bought my 29)
A decent price when we realize that a basic logitech does not work on many surface is 49!
