    Rated 4.1 out of 5�by 137 reviewers.
    Rated 5 out of 5�by Awesome Keyboard/Awesome Price! I am a Medical Transcriptionist so I need a GOOD ergonomic keyboard since I am typing 40 hours a week and I need to type FAST! This is the BEST keyboard and it was $19.00 off, so I only paid $30.95, which is a CRAZY GOOD PRICE for such an awesome keyboard! Even at full price, it is worth it! I have paid up to $80 for other similar ergonomic keyboards that were not as great as this one is! It is also VERY quiet, and believe me, I POUND THE KEYS, and I work at home, so with the quietness of this keyboard I am not waking up other household members when I am working my shifts that start at 6:30 a.m!

    Rated 5 out of 5�by Great ergonomic keyboard Love this great for my hands, especially since I have carpal tunnel. September 28, 2015
    Rated 4 out of 5�by Ergonomic Keyboard I was having wrist/forearm problems due to more typing at work than normal and a friend recommended an ergonomic keyboard. After a week or so of use, the pain is gone. It takes some adjusting before it's comfortable, but not a problem after a couple of days of work. Definitely worth trying out if you have soreness in your wrists or forearms. September 28, 2015
    Rated 5 out of 5�by Wonderful for my wrists This is my fourth one so far. I usually wear the letters off, was forced to replace again as my dog chew on the cable. Love it. I cannot use any other keyboard anymore. I spent most of my days typing and this is just great. August 24, 2015
