Pros: If you happen to have a ton of other blue lights on all of your other accessories and components, this keyboard really fits in well. The backlights adjust well, and aren't too bright. Keyboard is incredibly responsive, and, so far, feels great. Obviously not a mechanical, but for the price, you cannot do any better than this.

Cons: Nothing considering the price.

Other Thoughts: I'd buy this again if it wore out in a year. Heck, I'd buy it again if it wore out in 8 months.

Pros: Backlight is great.
Macro button locations great for me.

Cons: Backspace button is really stiff! A tap doesn't do.
Enter button gets stuck! really sucks as I'm coding...
Although the back light is bright. I don't see it clearly as I use my keyboard laying down.

Pros: Neat blue glow
Font is nice and futuristic
Buttons for profile modes
Quiet typing / gaming
6 Macro / custom keys
Slightly textured keys
Good look (better than regular Skiller)
Braided cloth covered USB cable
Remembers settings through sleep

Cons: No way to save settings for non-profile mode
Only 3 profiles (but can save / load profiles)
HUGE Enter button (Moves '| \' key next to smaller RShift)
Defaults to 'breathe' mode when turning off gaming profile
Also defaults to 'breath' mode on reboot
Have to use FN key to turn off gaming profile mode
Updating the configuration feels like it takes a long time sometimes

Other Thoughts: Overall I would say that this is a very nice keyboard and if you're looking at it over the original Skiller, I would say definitely it is worth the extra $5 to get this one. The backlit keys are neat and the keyboard overall has a good feel. My main selling point was the Macro keys on the left and the backlighting. I could do without the "media" keys, but they are out of the way on this keyboard. Most of my cons are really nit-picky, but the only complaint I have is that I don't like the "Enter" key style. Occasionally it causes me to type "|" instead of "?". Overall, a very nice keyboard at an inexpensive price.
