I have a claw grip, and small girly hands. This mouse is not quite right, but is definitely much better than a lot of others I've tried. I may upgrade in future when they come out with a Model O Mini Wireless, but until then, this definitely exceeded my expectations. It is light, easy to move across both a naked and a mouse-mat surface, and I have had almost an 80% decrease in sweaty palms while using this mouse. Admittedly, I'm not a heavy gamer, but I find this responsive, easy to use, and very comfortable. Its customisation (including RGB lighting, macro mouse buttons and DPS settings) is increased when you acquire the software (for which you're provided a link in the box), and its use is intuitive – I would even surmise that this could be used by even the boomiest baby boomer. 9/10 – I just wish they came out with the mini at the same time.
