Summary: The difference between membrane and mechanical is light and day. Never again will I have a cheap keyboard! The cherry red switches make for an effortless and enjoyable time both while typing and playing games. It didn't take very long at all to get used to this keyboard, and it seems typing has become easier than ever. As others have said, the wrist wrest is uncomfortable and has been solely dedicated to key cap storage.
Summary: Very nice keyboard, it would be better if it had lights, so I could play in the dark. the good thing about this keyboard is that its nopt loud compared to the razer ones. and the red button adds a cool feature to the keyboard as well.
Summary: This is hands down the best gaming keyboard I ever owned. Sure it's a gaming keyboard, anti-ghosting blahblahblah rollover. Yeah, it's got all that. What I wasn't expected was the workmanship on the keyboard itself, beautiful brushed steel and each key strikes with purpose. The exchangeable keys are easily removed and interchanged without any fear of permanently damaging your keyboard ripping keys out.
Summary: It's metal base is robust and keeps the keyboard in place, it will last for years. The keys are so responsive and fast, smooth yet almost clicky, Not mashy and mushy, but smooth with a slight firmness, or click. Nice textures for the special "gaming keys" Just wish it was wireless, but then again batteries are a pain to recharge.
Summary: The design is sturdy, the keys are nice and grippy. The hand wrest is in a great position and the keys are extremely fast and responsive. The ghosting of the keys basically doesn't exist, it updates your actions at roughly 1000 actions per second, great for FPS and RTS gaming. I cannot find a flaw with this keyboard, other than the keys are very loud (but its mechanical so I expected that when I purchased this).
Summary: At first, this keyboard was exactly what I was looking for. Worked great - keystrokes were well-defined and precise. Now - there are a bunch of keys that register multiple strokes on one actual stroke. For instance, the number 9 key on the 10-key side registers anywhere between 2 and 4 keystrokes on the screen. There are a handful of other keys that do the same thing. I have tried cleaning the thing, but it just doesn't make any improvement.
Summary: I haven't purchased or tried many keyboards. I have to say that this keyboard may be the only gaming keyboard I will have to purchase. I don't see the point in LED back lit keys so this keyboard is stripped down to durable and reliable parts. The grippy keys are a great idea but aren't that different in feel from the normal keys aside from the curvature of the key.
