Rated 4 out of 5�by 114 reviewers.
Rated 4 out of 5�by Great keyboard for carpal tunnel This is a great keyboard and has helped with my bilateral carpal tunnel significantly--this is my 5th or so. However, I am not happy that Office Depot's price is $20 higher than elsewhere and had I had the ability to wait and shop around I would have saved myself some money. Also, unfortunately, the letters on the keys are gone within a matter of weeks, requiring keyboard stickers. April 13, 2015
Rated 5 out of 5�by Ergonomic Keyboard The woman in our office who is using this absolutely loves it! She has had some wrist pain in the past from excessive keyboard use and she said this has really helped with that. March 30, 2015
Rated 1 out of 5�by No Manual Available I just got thie keyoard, it came with no manual. I have tried to find one online, but all I get are the iformation on the little pamphlet about the use of batteries, in 20 different languages. It seems to be a nice keyboard but the lack of a manual makes it unusable. March 23, 2015
Rated 5 out of 5�by Love it Grandkids spilled soda on my old keyboard and it bit the dust. I drug out the spare and immediately ordered this one. If you have ever used a "split" keyboard, you'll never go back to the regular one. On standard keyboards your hands are so close and shoulders cannot relax. On the split keyboard, your shoulders are where they're suppose to be. It takes some getting use to, but then you're hooked!! I would, and have, recommend this to anyone. March 10, 2015
