Pros: Wireless
Cons: Feels cheap, cheap scroll wheel, cord plug is meh.
This mouse is known for it's scroll wheel squeak for good reason, mine had it really bad and it drove me insane. The mouse is cheaply put together and feels cheap in hand. Like most razer mice is picks up those nice skin cell marks very quickly. Also don't expect to be plugging in the cable on the fly in mid scrim of anything, the plug is awkward. I would not waste the money on this mouse.
