seriously i regretted after i bought mx518, the material used to make the mouses.. i dunno how to say, but if our hand oily abit, must clean it from time to time, need to wipe strongly to remove those oil some more..

i've been using a4tech since i get my first pc.. but then, their mouse broke due to "hardcore usage".... i keep whack my mouse on the table when i died in a game, when i get mad... gamers, u know the drill =x so i jumped ship to test mx518 because theres alot of positive comment.. but when i switched *refer to first paragraph*

well, their mouses are cheap and has great feature.. even the lowest end also has 2x click feature.. which other brand doesnt have.. they're just a great company.. now im going to whack this mouse until it break.. and jump back to a4tech.. no no to razer and steelseries, too expensive
