This mouse is just great. For me, this is my first mouse really "high end" and I have no regrets despite a price can high. But then we must know what we want. Received the material has the expected date, even the packaging is great (it does detract pleasure). The first grip is a little strange but with some tweaks it quickly becomes natural. With a good carpet (Vespula) glide and responsiveness are just amazing. FPS fan, after some online games the difference is more than notable. I would not get the best shooter of the canvas but I find a new pleasure to play and at least I can not raller against my old makes me smile when I explode ... In short, if you have the budget, do not hesitate, this mouse (which no longer looks too much like a mouse) will delight you ... Hi all ...........................
