Summary: I bought this for my girlfriend and although it worked well for her, who prefers small mice, it would sometimes act up. It would lag a bit or jump to random directions. However, after she started using a decent mousepad, the problem went away and the mouse works like a charm!
Summary: As the review below, I also got this with my Asus G53JW-A1 purchase. The mouse itself if comfortable, however, it simply does not have enough buttons to be considered a gaming mouse. The lack of even a single thumb button really kills this. If I'm not able to consider this a gaming mouse, $49 is way too much to pay for a regular mouse. Not recommended. Tried to post as 2 stars, but I do not have an order ID since this was thrown in with the laptop.
Summary: Got the mouse free with my G53JW-A1. Feels too light and too small for my liking. Also the rubber feels cheap. The worse part is that the mouse only have 3 buttons. Even a $20 mouse these days for 5 button (2 on the side for easy web browsing and other simple task). Even the mouse I use in my office have 5 buttons. Will not be using this mouse since I just can't get by with only 3 buttons. My MX518 feels a lot more better and easier to grip.
Summary: didnt like this mouse at all, felt like cheap plastic. also wasnt comfortable to grip like my standard microsoft mouse. this mouse is very thin and flat... only good thing is the dpi adjustment.
Pros: decent dpi, led?
Cons: no sleeved wire, uncomfortable grip, strange cheap plastic material
