Hits the streets in September. http://www.bit-tech.net/news/hardware/2016/08/24/cooler-master-mastermouse-pro-l/1
I've always thought that having a configurable mouse like this just makes sense. I mean people's preferences change so wildly with peripherals: hand size, grip style, aesthetics, functionality etc. I liked how when I had a Razer Naga Epic you could change the mouse shape fairly considerably with the side portions. Being a member of the fat handed t*** masterrace it was nice to be able to make the thing a fair bit bigger. The mastercase was an interesting idea, but I think if CM get this one right it could be a real game changer.
The shape of the main body makes it look like it could be ambidextrous, but there are what look like thumb buttons on the left hand side of the body - are they on the right too? Being a lefty, I've had trouble finding a mouse that suits my sinister persuasion and also feels comfortable, with the choice of panels on offer, this could be interesting.
