This wired vertical USB mouse by Delock is suitable for right handers and can be connected to a free USB port of a PC or laptop. Due to its ergonomic design, the hand remains in upright position and does not have to be turned. Thus the mouse can be used preventive or with starting pain e.g. RSI (Repetitive-Strain-Injury).
