Pros Excellent feel. Cool design.
Cons Broke after three weeks. USB will not connect. Many other users on Newegg had this same problem. Don't buy! It's not worth the risk and the time!
Summary You can get a more reliable keyboard for the same price. Don't buy this one.
Pros Cherry MX Blue switches. Great build quality. Excellent key feel, comfortable to type on for longer periods of time. Laser etched keycaps are more durable than the pad printing most keyboards use. Braided USB cord is a nice touch.
Cons No frills. No PS/2 adapter in the box for N-key rollover (99 cents online though).
Summary Fantastic price considering the build quality. A keyboard's primary purpose is typing, and through a well made Cherry MX Blue keyboard, you get longevity, tactile feedback, consistency of actuation & earlier actuation, and audible feedback- all of which contribute to a longer lasting keyboard that is more comfortable to type on. Competitors have small touches but are nearly twice the price- as such, I highly recommend the RK-9000 as a result.
