I had heard so much about this keyboard as being a really good RD keyboard. I saw a seller on eBay selling these as still new in unopened box, PS2 interface with free shipping so I ponied up the cash and ordered myself one to see what it's all about.
The quality on these keyboards are very nice. It has some weight and doesn't move around the desk at all! I took a cap off and under the cap is a white slider that looks like one of the sliders I had on an old Compaq NMB keyboard from years ago. The responsiveness of each key press is very nice to me. They are not in the same league as a Topre switch but they are not meant to be. They give a nice thud sound when bottomed out and since they are RD, you will need to bottom out. This is not an issue for me. Actually I read in awe when GeekHacker's talk about red mx keys and not bottoming out while typing. I've never been able to do this but then again, I come from the Model M days and typewriters too!
So if you are looking for a good, no frills, rubber dome keyboard to keep as a spare or to use on a second PC or to even use as a daily driver for office work, I would suggest this keyboard. However, the name outright LIES "QuietKey"
? Only when you are not using it!!! LOL
The keys make a nice thud sound and it's quieter than a Model M or a clicky alps or MX blues but its not "quiet". If you need quiet I would suggest a nice scissor switch keyboard to use late at night.
I keep my Apple Bluetooth mouse around for the 2am work at my home office.
thanks,
