When it comes to mice, SteelSeries over the past few years has basically stuck with a single design that they have used on multiple mice. We first saw it with the Xai and later the Sensei but they have also used it on various branded mice and a smaller version on the Kinzu as well.

You can change lighting options,macros and button defaults and CPI steps to cycle through in the Steel series Software,but i really do not like the software and uninstalled it as the Rival 100 works fine without it. The Number of buttons are 6 but i use this mouse for cad and website design .

In terms of buttons, they feel solid.Side buttons are good too and Wheel click is smooth; Rival 100 is quite sturdy; Even the side grips have a high quality feeling to them; The Rival 100 works quite well set on 500 CPI I could also recommend use at 1000 CPI ,but none higher, which i wouldnt use...

Software; i had no use for; especially since i do not play the default games that is included in their software settings.So no way i am going to enable another start up item

Fast and responsive, cool lights.

It's good.. Lil bit heavier than my previous one Logitech G300 which I was using for like 3-4 years.. It's just lil bit heavier than my previous one. But yes once you get acquainted with Steelseries stuffs.. It's just cool.

While this mouse is good, it doesn't really feel comfortable in my hand, as some of the edges aren't as smooth as they look in the images.

Good tracker....very good design to play cs..but it would be better if the buttons were concave instead of being convex.

decent mouse for fps games, simple and smooth, well worth the money.

Very good for the price but doesn't have very many sensitivity settings and its lighter than I would like though well built. I like being able to have any colour on the lights though.

Today I will be reviewing the Rival 100 Gaming Mouse from SteelSeries. "The Rival 100 optical gaming mouse brings unmatched performance to PC and Mac gaming, armed with illumination, a best in class sensor, and six programmable

Smooth; glossy finish; Multi-color backlight; Correct weight; Color options

Really good mouse but not enough buttons for gaming IMO. Good button feel and resolution so a good mouse for Windows.
