Decent wireless and portable mouse; a little too small and light for my taste, but convenient to pack. I have been using a 'vertical mouse' for years due to carpal tunnel symptoms and extended gaming with the Impact III seems to have re-activated my symptoms. I wish it came in a vertical form factor. Additionally, the DPI change button and the LED colors seem gimmicky and the instructions less than clear. So far, under light use, it's a good quality product. No notable lag, but I don't play twitch-shooters as a rule. Overall a good product, with the caveats as stated. Battery life is pretty good too.
