DXT Mouse enables the hand to work from a relaxed position reducing the tension on the soft tissues. The unique ambidextrous design allows you to mouse with either hand with only the press of a button. The DXT mouse is held by the finger tips and not against the palm of the hand so it can be manipulated in the same manner as when using a pen. USB Plug and Play. Windows 7, Vista, XP, 2000, Mac OS 10.4 or higher.
