WOW TECH has a newer version of their ergonomically designed Wow-Pen mouse coming to the U.S. later this month called the Wow-Pen Traveler. The Traveler, like the “eco”, has a unique design that lets you hold it more comfortably like a pen to put less strain on your wrist and arm according the company. But this mouse also packs a few more nice features into is odd-looking design.
