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.
Summary: Very good deal for price. All keys are easy to use and feels nice. Cheap Look and no wrist padding just plastic. Dosen't have the bigger home keys and edge keys Y H N T G B. Has quick keys that work. I was most surprised by the ease of the buttons. Very easy to use.
