Desk Calculator DE-12E-WE

Ergonomically designed for right-handed users: The keyboard features an innovative stepped design with a 3° tilt from right to left. Compared to conventional desk calculators, this innovative keyboard design causes less torsion of the forearm and wrist rotation, as it adapts to the natural position of the fingers and hands. The stepped key shape allows for perfect vertical key presses, making typing easier, reducing strain, and helping to prevent repetitive strain injuries (RSI). This reduces the muscle activity of these three muscles: pronator teres, extensor carpi radialis, and flexor carpi radialis.
