Cons: I will say that the scroll wheel is somewhat missed, the "notches" that allow to distinguish between the different weapons during a switch at stake does not give me the impression that they will last well over time (warning I speak here of an impression not a proven fact). In addition, the sliding pads placed under the mouse are equally "misfire". Indeed skiing is more than perfectible, to tell you, I was before this mouse on a mouse to a noband thirty euros gliding much better, and on any type of surface.
Conclusion: Excellent quality / price ratio, you will only find little (no?) Competing in this price range. Ravieront serious advantages that you for sure.
PS: sumptuous Packaging. (Argument to consider in my :-))
