The keys on this have an amazing feel. The keycaps themselves have a slightly rubberized feel to them and have a very nice feel when pressed without making significant noise. I first ordered one to use at work, and after having asked around no one had any complaints about noise.
In the end i had to order a second one to use at home, because i kept mistyping otherwise because the keyboards were so different.
The only downsides i can think of are:
* The chassis itself, while solid, does not match the premium price tag (though the keys do)
* On a slippery surface the keyboard tends to slide on the side without the USB cable. This is partially due to a unbalanced weight distribution, and partially due to only having rubber feet at the front, and not on the back.
* The return and backspace have a different feel to them and sound much more springy which i don't really like, but the overall feel is still far superior to any other keyboard i have tried.
* Price... This keyboard is pretty expensive, you could probably buy 10 low cost decent keyboards for the price of one of these. And yet, i ended up ordering first one for work, then another for home...
