I got the keyboard today. It is a very high quality look and feel. However, the keys themselves do not light up very brightly. Also the feel of the keypress is kind of dull. That's the only way I can describe it. Makes me actually crave the click :/
That said, it really does do a FULL color spectrum of backlight. You can have up to 5 profiles with the software. Personally I use white all the time. I only cared about the white backlight; although being able to change the colors is cool. Also it gives thee option to turn off the Tt big red logo light, with each profile. This is nice.
There are programmable macro keys on the right and left. It takes a bit of a learning curve though and I'm still not sure how to define it was a key. But, it makes it easy to link it to a program.
You need to make sure to click the "upload" button in the software after you finish. But there is a popup that reminds you to save if you try to close the software without saving. Then after you save, you need to click the profile key on the keyboard to switch to your new profile.
The minus key for some reason does not work (the one next to 0 above the letter keys; the number pad minus key works). All the other keys work fine. The plug-in hand-fan is pretty cool (no pun intended); although I found it was a bit cold. But good if your room is warm. There is a large port on the top back left (facing monitor) in which you can place the hand fan when you are not using it.
The keyboard actually has two onboard USB ports for plugging in other things. This is useful, you can plug a mouse and other things in; although it does not provide enough power for a 2.5" external HDD. It also has a physical headphone and microphone jack (although when I use a microphone I use a USB microphone).
Overall, although the keys could be brighter, it is a good solid keyboard of sturdy construction.
All that said, I just bought the Logitech G110
also. I liked how it has an individual LED for each key - hopefully the keys will be brighter. It also allows to customize it to be whatever color you want. It's a good price, too.
I am going to try them both and choose one. Then I will sell the other.

I was going to get the Luxeed U7 Crossover
, but I couldn't find it anywhere. I think they have been discontinued and I don't know if the company is even in business anymore.
