Elite Adjustable Keyboard can help support your posture and the angle of your wrists, hands, and forearms when typing, reducing the risk of Repetitive Strain Injury (RSI). It’s the most versatile ergonomic keyboard yet, allowing adjustment of the keyboard horizontally from 0-30 degrees and vertically from 0-60 degrees. Tenting and splaying the position of the keys to your preferences prevents injuries by offering a more natural typing position, taking the pressure off the tendons and joints.
