Evoluent - Inventor of The Vertical Mouse - VMDMW Ergonomic Vertical Mouse Right Hand Med USB Wireless, Sculpted for Comfort, Reduces Wrist Strain, 4 Speeds, 6 Customizable Buttons in Windows

Features

• UPRIGHT HANDSHAKE POSTURE: The VMDMW holds your hand on its side, the way it sits when you shake hands, instead of rotating your forearm flat against the desk for eight hours. That one change is the whole point of a vertical mouse, and you feel it inside the first hour.
• MEDIUM SHELL, THE MIDDLE OF THE RANGE: Fits most adult right hands. If yours is noticeably small or large for its shape, the same design is made in the two sizes either side of this one.
• WIRELESS ON A USB RECEIVER: The receiver goes into a standard USB-A port and the mouse is ready. No pairing screen, no account, and basic button and wheel functions need no driver.
• SIX BUTTONS, AND YOU DECIDE WHAT THEY DO: Install the free Evoluent Mouse Manager on Windows and give every button a job, including a different job in different applications. Undo, close tab, double click, screen brightness, whatever you reach for most.
• FOUR POINTER SPEEDS ON THE MOUSE ITSELF: Step the cursor from slow to fast with the speed button and read the current setting off the indicator lights. You never let go of the mouse or open a settings panel to change it.
• A LIP THAT KEEPS YOUR PINKY OFF THE DESK: The broad lower edge gives your little finger somewhere to rest instead of dragging it along the desk all day. It is a small detail that shows up by mid-afternoon.
• THE ORIGINAL VERTICAL MOUSE: Jack Lo invented the vertical mouse in 1994 and Evoluent shipped the world's first one in 2002. Every curve on this shell comes out of more than thirty years spent on a single question, how a hand should sit on a mouse.
