The 450K keyboard is all plastic, and it feels well-built for its size with little flex. It has smooth plastic on the top and bottom of the keyboard, with a brushed-plastic finish in the centre. The finish is a nice touch, as it means the keyboard avoids picking up fingerprints and smudges like the aluminium of some of its competitors.

The Cherry MX hybrid mechanical switches have three-colour backlighting and are completely sealed, which the company claims makes the keyboard waterproof. It stood up to that task in our testing, but Hardware Canucks still recommends against undersea computer usage.
