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

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

Fast and responsive, cool lights.

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

Solid ergonomic design; Inexpensive; Angle snapping; acceleration; and deceleration; Excellent optical sensor; Stores profiles for each application and game

Only switches between two dpi settings; No lift-distance control; Macro creation lacks depth; No sleep control when mouse not in use

Light, comfortable, accurate, fancy glowy colors. If it's comfortable in your hand, there is no reason not to buy this.

I have large hands and use a finger tip grip; This is a big mouse and I love the feel of it in my hand; The rubber texture is nice and makes it very easy to pick it up during fast paced FPS games.

I had a couple of failures and had to exchange it for another one; Could have been a problem with my motherboard's USB port, but not sure

If you like Dota 2, you will definitely like this mouse, like I did, plus you get an item for Doom. Its called Hell's Glare, looks very good on him.The best part about this mouse is the customization.

I bought this along with a qck mouse pad and the mouse feels great with it , response and feel is great on it . great engine to dial it in and greatvcolor combos to make it to your liking .
