Comfortable and a good weight. The buttons feel great and the additional sniper buttons is nice for certain games/tasks. Everything I wanted in a mouse without any gimmicky features.
Like many other mice on the market, this one makes rather extravagant claims. In use, on the desktop, it's pretty much just another mouse. This one has better latency than some other mice, but I've never understood why so many mice have high latency. USB, by design, is supposed to be low-latency. I could summarize by saying this mouse delivers exactly what I would expect from cheap mice. "Gaming mouse" is a silly term, IMO.
