I bought this mouse for its low price, expect a lot. I thought observing latency between his movement and the cursor and in fact, bah not. It is small, ergonomic, highly reactive and has 5 buttons (plus a rule that not). It consumes very little (supplied with LR6) and is as solid as most mice I had. In short it is excellent, I can use it to play no problem, and I do not have this thread bothers me in my further movements. A great surprise for me, enough to have taken second after the first wear.
