First, I bought this mouse in September 2014 as its price is considerably lower than that of competition compared to what it offers. Level ergonomics, it is conclusive that she does not fit as well in my hand a Logitech G500 for example. Key programming is very simple and very comprehensive, it can be assigned to functions / keys do not appear on the keyboard (like the "mute" for example). However, I notice a problem with the wheel for more than a month: open game, sometimes the wheel to my assigned function (here the Zoom / dezoom) activates itself! This is very annoying! The finish of the mouse is in line with its price: there is a slight play in the keys on the side but it is absolutely fine for the price. In addition, the plastic top of the wheel is smooth and slightly lack of adhesion.
In conclusion, do not expect to buy a mouse gamer at 70 (compared to the choice of materials, finishes, "reliability"?) By purchasing this mouse! However, hard to beat at the price it is sold!
