My first G300 started asking me problems after 2 weeks of use ... The right click "holding" more. In an MMO that requires turning the camera still pressing the right mouse button, the problem was MAJOR. I did replace the product by the dealer and the new mice behaved in exactly the same way one month later. I finally turned to another model (G700) and finds no fault this time.
Also note that the 2nd G300 also had a wheel problem: a "notch" was more rigid than others (with an unusual rattling noise) and the next too soft, which had the effect of skipping a step in the scroll . No big deal for the office but we speak here of a mouse "gaming".
In short, I absolutely do not recommend this model.
