For $60 this mouse is just great. I'm amazed, I really never thought wireless would ever completely overtake wired in terms of gaming performance. I've been playing CS for so long that I started with a ball mouse and I still remember my first optical mouse. Wireless g305 is a discovery on the same level. In a word, the sensor is ideal. I feel absolutely no difference between this mouse and my 3360 Nixeus Revel, 3310 Zowie Za12 and wired G Pro. I've played a lot with these and many other high-end gaming mice with quality sensors, and this G305 feels as good or better than any of the others. The double shape and slightly smaller size than the average mouse has always been my special cup of tea, and this mouse is just that. It's pretty light, too. For me the perfect mouse. It might not meet all your needs like mine, but if you're worried about the wireless sensor not stacking up, don't worry. It's immaculate. Well, if you don't like two-handed mice or have giant bear paws for hands, then maybe I can see that this isn't for you. But if, like me, you've been waiting for a truly no-compromise wireless gaming mouse at an affordable price, congratulations my friend, your wait is over. Go and buy that thing right away. To be honest, I don't see why anyone would pay $150 for a wireless G Pro when it's just as good and less than half the price.
