If you have carpal tunnel or other wrist/elbow issues this keyboard is for you! It helped me when I was dealing with wrist pain several years ago. It's sturdy, with a steel base. The three sections of the keyboard can be moved to fit the width of your shoulders. They slide off the base so their order can be changed (depending on whether you type predominantly text or numbers). The keyboard sections also rotate in all directions to accommodate preferred and healthiest wrist alignment for your body. This cost $250 new when I bought it! Please text, can be viewed evenings and weekends.
