This gaming mouse from Rii is a great little product that covers all the basics you might need at a really fantastic price. It has three additional buttons that you can program, the LED lights look really nice, and you can switch the DPI settings on the fly. Plus the price is super low for a mouse like this, so it's very affordable.

The mouse is designed to fit around your fingers, but sadly I found it was just too big for my hands. My husband had no such trouble and found it very comfortable, so if you have small hands maybe keep that in mind. I consider myself to have medium ladies size hands, but this is definitely made for large hands.

One other issue is that the LED lights cannot be turned off or adjusted, they will change colours the entire time. The lights aren't too bright so it never distracted me, but not being able to adjust them might annoy some people.

I liked that the mouse had 4 sensitivity settings, so I could easily switch depending on what kind of game I was playing. I would have liked some indicator of what speed I was setting it to, so I didn't have to frantically wiggle the mouse each time I changed it until I got the right setting, but that shouldn't be an issue unless you change often and in the middle of a game.

Overall, this mouse does a lot of things right and I'm very impressed with it!
