Wireless Vertical Mouse
PREVENTS WRIST DISCOMFORT – Vertical Mouse 4 gently supports your right hand in an upright neutral position and has 3 buttons. The patented shape prevents you from twisting your forearm like what you usually do with an ordinary mouse.
ADJUST MOUSE-SPEED FROM LOW TO HIGH – You can adjust the pointer speed from low to high with the optical sensor controls on the side of the mouse. There is no need to release the grip for speed adjustment.
