Pros: Lots of buttons, good sensitivity, Looks pretty cool and its program that it comes with is easy to use.

Cons: About 5% of the time when I started my computer my mouse would not power up. I got looking into the problem and found that the mouse comes with a paper stating that sometimes when booting the mouse does not get enough power and the driver does not initiate. It then tells you to restart the computer. I did this and it worked about 80% of the time, the other 20% it still didn't work and I had to restart yet again. Restarting my computer three times to get my mouse to work kind of irritates me.

Overall Review: If you do have this problem the short easy way to fix it is using your keyboard navigate to your control panel, go to system, get up the hardware tab and press tab to get to device manager. Delete the device with the exclamation next to it and alt+f4 to get out. Go to add hardware and click it. It got it working every time for me. Of course, now I have a different mouse :)
