Pros: When I first got it I loved the keyboard: great design, cool look, worked well, etc.

Cons: After about a month the back light on the 'M' key went out. A couple weeks later the 'Pause Break' key went out as well and then the 'R' key. At first it wasn't that big of a deal because they were only a couple. Today the 'A', 'Z', and '4' all went out. If this rate continues half the keys won't light up by the end of the year. I just had higher expectations for the keyboard's durability, especially the light features, which was the reason I bought it in the first place.

Overall Review: Cool keyboard but don't be surprised if the backlight on some keys goes out.
