Rated 4.1 out of 5�by 124 reviewers.
Rated 4 out of 5�by Great Ergonomic Keyboard This is the 4th keyboard I have purchased of this variety. I haven't found a keyboard that I would purchase over this one. June 30, 2015
Rated 5 out of 5�by Works and performs as expected Very happy with purchase. Exactly as expected June 29, 2015
Rated 5 out of 5�by Best Keyboard EVER If you've ever had problems with your wrist due to typing, this is the keyboard you need! I've had 4 of them and won't use anything else! June 1, 2015
Rated 5 out of 5�by My favorite Keyboard I have bought a few of these and am always happy with the product. I have gotten them wireless and wired. The wrist rest is perfect when using the product ergonomically (Flat, you should never add the booster base or use the kickstands unless using both at the same time to raise the whole thing for your height) I love the extra buttons for usability (scroll, calculator, volume, play/pause, home, mail, etc) The spread on the keyboard is perfect for me, but I could see it being too wide for someone who was more petite. My oldest one of these is 3 years and looks almost as good as the day I bought it. Make sure to clean it often and it will treat you well. The only wear is on the space bar where it has been worn shiny. Otherwise good to go. May 14, 2015
