From GamesReviews: Across the board, everyone who has used this mouse have commented on the durability of the product. For general use, this is a really nice mouse and for those that want a great experience, the $100 is worth it. The downside? This mouse is pretty heavy for competitive players!
COG writes: The SteelSeries Rival 5 offers a wide array of features in its default settings but truly transforms with the help of the SteelSeries software engine.
The Rival 310 from SteelSeries is a wallet friendly mouse with tournament level quality and features. A must buy for anyone looking for a new gaming mouse.
Remember the last time your mouse kicked the bed and you had to use that crappy one that came with your setup? Back it up with this $30 option.
That is what we did. We had a couple sent to us and when my EVGA Torq had to be replaced, I used this one while waiting for the replacement. I still have not switched them as it works great.
