I'll go the way of previous reviews because it is a very good wireless mouse. She adapted directly to my computer (which does not new, it is the least we can say). Furthermore I am under linux and this mouse was recognized without any problem (for the skeptics who say that there has linux driver problems, which is wrong all my equipment is recognized without the need to install drivers. ..). This is a mouse that is comfortable with its flat shape and not tiny as can be seen (I have big hands) although it is also appreciated girlfriend having small hands. The idea of two sensitivity positions is very well located and well appreciated! This is a very classy and mouse that does not flashie multicolored strobe lights, fluorescent etc ... (which would have been foolish enough to a cell mouse). Incidentally stack air to last very long. Anyway a rechargeable battery and is quiet for years ... Sleep mode also extends the life of the batteries. Good thinking that, too. In short, mouse to buy eyes closed !! In addition the price is really reasonable!
