5 out of 5 eggsA Solid Choice for Mechanical Nuts

Pros: Blue Cherry switches feel great
Has a good heft to it, so it doesn't move
USB cable can be detached for neater storage
Good response and no ghosting
Adjustable LED backlighting looks great

Cons: LED settings are not stored when powered down

Other Thoughts: I am very happy with this keyboard. It looks great, feels great, and the only con I can give it is minor. I already knew about the LEDs resetting thanks to other reviews for this product, so it barely even counts as a con. I bought it for the blue MX switches, not the light-show. Besides, depending on what I'm doing on my PC, I prefer different LED settings for different tasks, so I'd be retooling it a lot anyway. If you don't have a problem with it either, then you won't be disappointed with this quality mechanical keyboard.

3 out of 5 eggsLights Out

Pros: Newegg support was excellent.

Cons: Lights do not come on after computer reboot. Must hit FN and F number keys each time. In my case, three F keys. F11 for lights, F10 for arrow keys and F9 for WASD keys. I called Rosewill Tech Support and the tech said all he had to go by was the instruction book which does not cover the issue. In a nutshell, tech support (in my case) was nonexistent. Newegg support for my order was excellent.

3 out of 5 eggsGood Keyboard

Pros: Cherry Blue switches - feel great.
Back-lighting looks awesome - which makes the con worse.
Skid pads on the back are solid.
Overall solid, heavy feel.

Cons: No memory, so it doesn't remember any LED light settings; meaning you have to reset it after every reboot/sleep/power off. For my personal taste in LED color that's about 5 or 6 key presses, but after every sleep/reboot its a pain and I'll leave the thing non-illuminated 95% of the time. Would be 5 stars if not for this.

Other Thoughts: Keys feel slick, like a well used keyboard.
Number/special char thing was zero issue for me. I know what that row does and, when illuminated, the numbers are lit up.
A few keys are the opposite though, LED lights light up the top portion of all keys, so on some keys it lights up the character that would normally be shift enabled (semicolon for example).

Bottom line IMO, feels like a solid mechanical keyboard with Cherry blue switches. Buy it for that and mostly forget about the back-lighting. If you want the back light, look for another model/brand that has a memory feature. Coming from a Razer Blackwidow I'd rather have the Razer.

3 out of 5 eggsSome "Shifted" Keys not on "Top"

Pros: Completely detachable/replaceable USB cable. Backlighting works nicely.

Cons: The keycap printing on the "number row" (the row of keys just below the function key row) shows the "shifted" characters BELOW the "unshifted" characters. For example the "8" key shows the asterisk BELOW the "8".

Other keycaps on this keyboard have the "shifted" characters printed above the "unshifted" characters, as is customary.

There's a high potential for confusion when creating passwords using characters on the "number row".

Other Thoughts: This was not a "cheap" keyboard and its otherwise quality features are marred by the "number row" keycap print inversion.
