Ergonomically designed Calculator for right hand users.
The keypad is configured in an innovative staircase design, with 3° inclination from right to left side.
Compared to conventional desk calculators, this causes less underarm torsion and hand wrist rotation, as it adapts to natural finger / hand posture. The staircase key shape enables perfect vertical keystrokes and thus eases the key typing, lessens burden and helps avoiding Repetitive Strain Injuries. The staircase design keypad causes less strain of the pronator teres muscle, the extensor carpi radialis muscle and the flexor carpi radialis muscle
The keys are extra easy to operate, and the key caps are ergonomically shaped (concave / convex) and are extra shock-absorbing for less fatigue of the fingers even in full-day operation.
