At first glance this mouse is top, I'm used gamer mouse ROCCAT, razer, logitech ... Coming from a Logitech MX510 and MX518 and ROCCAT KONE I found this mouse not bad, but grip level is slightly confusing when we used mice mentioned above, because one of these is a little too wide on its base and strength to put through its handle. But after two days it s' to get used perfectly, it is pleasant to the touch, do not score well on the mat slips and solid. I have unfortunately not kept because the wheel had a design flaw, but I think (after test) is exceptional.
