I've tried Corsair mice in the past, but I've had no success getting profiles to save to the mouse so that I could use it on a different PC. I have a work computer on which I can't install anything, so I need to be able to configure it on my PC.
The software is nothing special, but it works. It's only a 3MB download and it doesn't need to be running in the background. Go to redragonzone.com, select your model, and download the software.
Aside from that, it's a bigger mouse which is good for my hands. The only complaint I have is that the scroll wheel only lights up if the mouse is plugged in (red for charging, green for charged).
