ThinkComputers posted a review on the Cougar 600K Gaming Keyboard
A quote from the article:
Back in December we took a look at Cougar's flagship gaming keyboard the 700K, which took home our Editor's Choice Award. We are moving down Cougar's gaming keyboard product stack and next up is the 600K. The 600K is a small step down from the 700K, but it still features the same aluminum chassis design, mechanical key switches, repeat rate buttons, FPS palm rest and more. The only real big difference between the 600K and 700K is that the 700K has the 6 extra programmable G keys and individual key backlighting. The 600K still makes for a really great keyboard and has a complete feature set that many gamers are going to enjoy. Read on as we take a look?Cougar 600K Gaming Keyboard Review @ ThinkComputers.org
