Pros: Cheap, 7 keys, weight customization, on-the-fly DPI shifting, 4D wheel
Cons: Size, spider emblem (I don't really like it)
The two things I don't like about it are the size and the spider emblem. The mouse will not fit in all hands, it is a bit better for claw grip. Although I used to have a palm grip before, I've got familiar with it. As for the spider emblem, I just don't really like it, a plain black body would have been better.
