Pros: Fast, great stats, great price for 1TB.

Cons: Clicks every once in a while.

Overall Review: Running Win 7 Ultimate 64 bit on it with around 500gb of programs and games installed, everything is working fine. Defragged multiple times and also ran a 2-3 hour test on it and everything checks out perfect.

Pros: Great sound with games, music, movies, anything. Mic sound was good when it worked. Comfortable if you don't move around much.

Cons: Mic suddenly stopped working after a few weeks. Very thin flimsy cord like that of cheap ear-buds. Kind of balances on top of your head, moving around too much or looking down etc, it falls off. Very cheap appearance, if someone who didn't know much about headsets saw these, they would assume they are $15 superstore headsets

Overall Review: Luckily the mic stopped working right before the 30 days was up for return. Have owned plenty of Sennheisers and they always break on me pretty easily, usually physically though. Sound has always been great and I haven't had any break on me when it wasn't my fault like these ones. Will probably buy another SteelSeries instead, or possibly try a Creative set.. SteelSeries have always been fantastic for me though, and they are tough as nails.

Pros: Works fine with a new battery, and with Win 7 Ultimate 64 bit which I installed.

Cons: Came with a battery that lasted less than 5 minutes if not plugged in.

Overall Review: Had to spend another $30+ on a new battery, I know I could have RMA'd it but didn't want to wait. Probably could have bought a bit better laptop with the extra battery money.
