Pros: Light. I know it's a con for some people, but for me it is the light weight I wanted. I bought this mouse to play battlefield 3. The 10 dollar M100 served me well, only that I wanted to switch sensitivity on the go. during infantry combat/inside a tank I prefer low sensitivity but in a AA I want high sensitivity. The dpi switch of g100s does the job so Im happy with it. It's slightly heavier than my cheap m100 but with the little extra weight it brings stability also.

Cons: Cord is stiff, but as a low end gaming mouse u can't expect much. Price. I bought this when I was in America, when I came back to Asia I found the shops here sell it cheaper($28 in the shops, $20 online). America has the cheapest price for most electronics, not this one.

Overall Review: After 11 months of gaming the left click started malfunctioning. I don't put this as a con coz I believe it is a reasonable mileage, and for the time it worked it served me well. I am planning to buy another one.

Pros: does its job. eliminated the cumberness of tangling wires.

Cons: the joint between plastic part and the metal breaks after 1 months of use. Only with extreme caution every time putting it on/off can make it last longer.

Overall Review: If you think 70 bucks for 1 month of use is not acceptable, DON'T buy this product. To a poor guy like me, it's certainly not worth it.
