Initially I planned this purchase as backup or mouse for when I am led to move with my laptop. In the end I was pleasantly surprised by the qualities of this mouse under its price. First of all it is convenient daily by its compactness. Housing is provided in the single AAA battery compartment for the USB dongle. But in the end it is more "all-terrain" that my logitech M555b which is however much more expensive! Indeed its sensor works on virtually any media, even glass. I use it daily since my purchase and I have not had to replace the no-name battery that was shipped with, therefore the autonomy seems satisfactory. In short this time a good product at a great value price.
