Summary: I purchased this keyboard hoping it would relieve stress on my hands when gaming. It not only did that, typing on it is much more comfortable than a normal keyboard. It does take a few days to get used to. The keys make a bit of noise, however not much more than any other keyboard. I recommend this keyboard for anyone who would like a more natural placement of the hands when typing, highly recommended.
Summary: I bought two of these quite some time ago, one for my wife and one for myself. As a programmer I spend my days tickling the keyboard and mine wore out in about a year. My wife's is still going strong but hasn't seen near as much use. If you're not going to ask for a long useful life of this keyboard, it's a good enough value. If like me you expect millions of keystrokes per year, keep looking as this one will let you down.
Summary: I've used this keyboard at my last two jobs and am quite satisfied. Using a normal keyboard plain HURTS, but this one is quite comfortable for me. Be warned if you have a small space for a keyboard that this thing is HUGE and heavy. Feels VERY solid, performs flawlessly. I'm not sure what makes this look cheap to others, other than the low price.
Summary: I had this keyboard for about a week and I decided to stop using it. It has a cheap look to it and performs terribly. Many of the keys would often stick on me causing them to type several times in a row or they wouldn't work at all. And it wasn't very comfortable to type on with carpal tunnel at all. I'll be going back to a Microsoft Natural Ergonomic Keyboard 4000. I highly suggest you not purchase this keyboard.
