Experience the relief that only a natural mousing grip can offer, by switching to the Penguin Vertical Mouse - Wired Large. The Penguin Mouse is easy to set up and offers precision mousing with laser tracking and variable DPI settings. With USB compatibility for Windows, Mac OS X and Linux operating systems, it's ready to go right out of the box. Unlike most ergonomic mice, the Penguin Vertical Mouse - Wired Large can be used by either left-handed or right-handed users, making it an excellent option for shared computers or for users interested in ambidextrous mousing.
The traditional mouse is quickly becoming a thing of the past, thanks to improved research on the mechanics of the muscles leading from your hands to your wrist, all the way to the shoulders. As it turns out, gripping a mouse is an unnatural motion, one that can lead to a variety of strain injuries, especially when compounded over long periods of time. A vertical mouse such as Posturite's Penguin Mouse has been designed to reduce such fatigue. If you've been experiencing any kind of hand, wrist or arm pain, try one for yourself and you'll be amazed at the amount of relief you experience.
