I like most Logitech accessories, but this particular keyboard has the wrist support that I like, and has been a trooper through everything. The mouse wasn't as sturdy, and was replaced with a razer which is the Cadillac of mice, and I got a matching set of razer headphones to go with it.
You've got more than one color in your glow. That'* got to be too pimp to calculate!
There are actually 5 different sections to the keyboard each with its own set of led'* that can be programmed to 5 different colors and different brightness levels. This is all done with the little touch pad on the top of the keyboard.
