We have been checking out Cougar's gaming keyboards over the past couple of months. We first took a look at the high-end 700K, then moved down to the more minimalistic 600K, and today we will be taking a look at the more entry-level 500K. This keyboard is actually quite a lot like the higher-end 700K, it has the same 6 programmable G-keys, N-key rollover, a 32-bit ARM processor and on-board memory, the FPS palm rest and more. What it does lack is the aluminum design and mechanical key switches. So if you are not a fan of mechanical key switches this could be the keyboard for you. This has to be one of the more fully-featured non-mechanical keyboards that we have seen lately. Let's jump in and see what this keyboard can do!
