Pros: -4 buttons -tiny usb transceiver (I can leave it plugged into my laptop when I put it in a bag without it getting caught or broken)

Cons: -scroll wheel spins smooth instead of in increments

Overall Review: I bought this so that I can game on my laptop when I'm at friends. It certainly isn't as good as my expensive desktop's mouse but its the PERFECT surrogate for when I'm stuck playing on my older/slower laptop.

Pros: Good all around keyboard: -looks awesome -feels great -works as expected

Cons: ONLY available w/ red back-lit keys

Overall Review: I spilled coffee on my old Logitech G13 and didn't have the cash t replace it w/ another logitech G-series but for the price this keyboard makes a impressively satisfying replacement...I will definitely look at sidewinders when it is time to replace again.

Pros: stay on my head while jogging better than anything else I've found

Cons: sound bleeds out because it is difficult to get these snug, sound quality could certainly be better

Overall Review: This is the second set of these I've owned. I use these while i exercise. I can't find anything that stays on my head better for a comparable but I have different set for serious listening.
