Evoluent Vertical Mouse 4 Wired, Goldtouch For Office Use

The Evoluent™ VerticalMouse™ 4 Wireless shares the same benefits as the wired version, including a comfortable, ergonomic design that helps many users relieve wrist and arm pain. This wireless mouse features a 2.4 GHz receiver to keep your desk free of tangles.
• A better way to grip: The vertical mouse is just like a horizontal one, just flipped to the side to help reduce strain. You can expect the same amount of pointer control accuracy and speed, all while keeping your arm and hand in a relaxed handshake position that eliminates forearm twisting.
• Fits every user: Large and small hands alike will both find their grip with the Evoluent™ VerticalMouse™ 4.
• No finger contorting: Features five programmable buttons you’ll be able to reach easily without straining your fingers or wrists.
• Prevents desk rubbing: A small lip on the bottom edge prevents the little finger from rubbing the desk.
• Variable Pointer Speed: A switch on the side of the mouse allows users to easily change pointer speeds between extra low (XL), low (LO), medium (MD), and high (HI).
• Just pair and play: Experience all of the advantages of wireless technology, right out of the box.
The Evoluent™ VerticalMouse™ 4 Wireless: a better way to mouse.
