The Corsair K63 wireless mechanical gaming keyboard is available in two variants, with the only difference between them being the color of the backlighting; there’s blue and ice blue. While we tested the blue LED variant, we expect most of our results to be valid for the ice blue variant too. There’s also a wired version of this keyboard, which has red LED backlighting.
The K63 wireless was designed to work with the Corsair Lapboard, which is meant for use with home theater PCs, as it allows you to sit back on the couch and still have proper support for the keyboard and mouse. It’s sold separately, but it’s often sold as a bundle with the keyboard.
