By operating the numpad with the hand that is not using the mouse, both hands remain within shoulder width as you work. The load will be equally divided between both hands. Ideal in combination with the R-Go Compact Break and R-Go Split Break keyboard. The ultra-thin design ensures that your wrists are in a natural, flat position while typing. The special scissor mechanism in the keys ensures a light keystroke, so you need less strenght to type. The R-Go Numpad includes a built-in break indicator, which indicates with colour signals (green, orange, red) when it's time to take a break.
