Ergonomic Mouse, High Precision Optical Vertical Mouse Adjustable DPI 800/1200 / 1600 Wired Computer Mouse (by Sharkk)

The traditional computer mouse model, although used universally in offices and homes alike, causes more harm than good with daily use.
Most computer mice operate by forcing your shoulders into a damaging internally rotated position, twisting forearms and causing wrist pain, shoulder fatigue and for many, Carpal Tunnel Syndrome.
The Sharkk Ergonomic Vertical Optical Mouse resolves these issues for the future and undoes damage from the past, encouraging users to shift their shoulders into a healthy and naturally-resting externally rotated position and
providing pain relief for right-handed users. Getting up and going to
the office might be painful at times, but that doesn't mean your actual computer work has to be.

Apart from its unique and modern ergonomic upright design, this Sharkk mouse is built or maximum efficiency with features like its rubberized grip, plug-and-play capability for easy setup and
installation and capability with most operating systems. Thanks to the added 'next' and 'previous' buttons located on the mouse's side (combined with the adjustable DPI settings), internet surfers can browse and scroll through
web pages faster than ever before. Once you adjust to using the vertical design, you'll never want to use a traditional computer mouse again.
