Having tried the logitech G500, G9x, Mionix 5000, Sidewinder X8, RAT9, RAT7 and Xai I can honestly say the quality in terms of materials and feel were not as good as some of these mice which are half and in some cases a third of the price! The mouse doesn't feel solid compared to other mice i've tried and it's also a little on the light side (again personal preference). The wireless and button feel on the other hand is good. I'm not a huge fan of the glossy material used on the sides which I found quite slippery. If your the kind of person to lift the mouse on a regular basis (while turning in an FPS or something) then you may get frustrated with this. I would have given the mouse a 4/5 if not for the outrageous price... I honestly can't see how they can justify this price with the flaws i've mentioned, just my opinion but not worth the money in this instance.
