Good mouse. The software supplied (download from the manufacturer's website) is complete and in line with what Madcatz for its rats 7 for example. The buttons are well made and taking excellent hand. The color change depending on the wheel and the logo is a nice bonus. Small problem I really did not happen to me at the right slice button: difficult access these may require an adjustment period. Otherwise perfect for a left in its shape and presence of 4 buttons this mouse does taf. Mention great sensor that can even run a scan of the surface under the mouse and provide information on the latter (% "excellence" of support). 90% with the mat vespula the way. In short good but the mouse buttons disappoint me right now.
