This wireless mouse is awesome! i cant believe what i got for the price that ive paid. build quality better than i thought, all the buttons clicks nicely without any weird noise or signs if they are not gonna last long and the finish is very nice, nice comliment for my alienware r315! it deffinetelly looks more expensive than it is. now since i dont really game that much anymore, but ive tried some games like rise of the tomb raider and this mouse just perform verywell almost without any lag at all! now to be honest if i game id preffer using my xbox controller anyways so if you play games using mouse and keyboard my opinion might be not enough reason for you to consider getting this mouse. my main purpose using the mouse is to edit photos and videos, and man there are so many buttons on it that i dont even think ill be using them anytime soon or even ever.LOL i saw the picture on the box it has many buttons so i thought maybe i could program those buttons to work with adobe premiere and some other photo editing softwares, but untill today i havent found a way to do it and i dont think its possible. but for what i paid for it, id keep it. i just wish id be a little bit lighter but hey, if its too light id wouldnt be called gaming mouse.
