Pros: I've had this mouse for about 3-4 years now and haven't had one problem yet (except for Razer's new Synapse software.. it just sucks). All of the buttons work like they did on day one, the scroll wheel and all have no flaws & all the lights still work although I never use them.

Cons: Long cord but can be tied up easily.

Pros: It types what I press. Keys are responsive and feel great to type on and game on.

Cons: Occasionally the keys would virtually stick, although the key is up, the button would still act as if it were down. If only I had taken that as a more serious issue earlier and RMA'd because now I am unable to RMA and the keyboard, after a couple months, disconnects and reconnects every 30 or less seconds. It's unusable for gaming and I will have to get a new keyboard. I've re installed USB drivers, keyboard drivers, tried all ports, even re-installed windows with no success.
