Summary: I love the way this keyboard types. It really is fantastic. The Cherry MX Brown switches are a dream. However, the way it uses usb is finicky at best. It randomly stops working for me, even with my motherboard that has USB ports that put out extra power (the support person at CM said that the keyboard works better with a powered USB hub since it draws a little more power than most). Don't get this keyboard. It's great when it works, but it's not worth the hassle.
Summary: Purchased this keyboard beginning of Dec, space key and left shift key were not properly positioned upon arrival. While able to jam back unto the metal spring they never functioned crisply. When I tried to take it apart, hoping to get all the keys on my 100 dollar keyboard to work correctly the [/u] cheap plastic casing it is made of shattered [/u] . Returning; will not buy cooler master product again.
Summary: Let me start off by saying that I loved this keyboard while it worked. However, a month after receiving it, the ALT key stopped working. I haven't dropped it, hit it, or spilled anything on it. It went out of the box and onto my desk and has stayed there. I contacted the manufacturer for warranty information, and after having to register for two separate support related websites, I was informed about the return policy.
