I have a pain at dorsal part of my wrist and since Ihave start use this keyboard I have feel a important improvement . it be ver y confortable if you have to type a lot but it be not a perfect option if you have to use a mouce frecuently -lrb- to scroll through image or similar ... -rrb- because it be quite wide and you have to move the hand a bit far from body what can produce shoulder pain . in this condition should be perfect to have a option without right part -lrb- that one with the number -rrb- .
