The Asus Vit W1 Laser Mouse does everything else your old mouse can do plus it has a pulse rate sensor that lies beneath its plastic skin. The wireless device has a 30 ft. range, 5 buttons, a mini-USB receiver, and 12 dpi. We don’t know about you, but just knowing that we will be monitored would make us nervous and have an elevated heart rate. Especially if the little happy face starts to frown.
