Most people would think wireless has a significant delay, this does not. I can't even notice a latency difference between this and my wired G Pro, and I have a 240hz monitor. The second thing people may worry about is the battery running out while playing, the battery has lasted over two weeks (with the light off) playing fast fps games for approx 5 hours every night. Using it while charging is not a problem as the cable is much more flexible than the old braided ones. I'm sure you could plug it in very quickly if it went flat on you. The shape, light weight and wireless makes for an extremely comforting experience even with my large hands (20cm long). Also if you game with your left hand it's exactly the same, I recommend watching “rocket jump ninja” review this on YouTube. I would definitely recommend this to anyone serious about their computer use, the logitech g403 would be my second choice if I couldn't afford this mouse because of my work/situation.
