I am currently using the CM Storm Mouse and Keyboard right now. So far, only a few complaints:
1. The mouse sometimes does not move when I move it and it delays ever so often
2. The keyboard sometimes stops working and does not type or function for a good 10 - 15 seconds
3. Keyboard is very nice with the blue LEDs
4. Mouse is great to match with the keyboard but isn't very reliable to use
5. Mouse has on the fly DPI change
All in all, if you aren't willing to spend a lot of money on mice and keyboards, these two products do function really well considering the price point. So yeah go for it.
