Deck keyboards are a line of premium keyboard input devices with unmatched backlighting capabilities. With Cherry mechanical key switches and one LED per key, we have the hands-down brightest keyboard illumination on the market. We can also say that without a doubt the letters on our keycaps will never wear off due to a process that prints the letter into the plastic instead of the top surface only. Backed by a 30-day money back guarantee and a 1 year warranty that covers your product even if you modify it, Deck keyboards are truly the last keyboard you will ever need.
