Evoluent – Inventor of The Vertical Mouse – VMDS Ergonomic Vertical Mouse Right Hand Small Wired USB, Sculpted for Comfort, Reduces Wrist Strain, 4 Speeds, 6 Customizable Buttons in Windows — Open-Box, 48% Off

UPRIGHT HANDSHAKE POSTURE: The VMDS 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.

SMALL SHELL FOR SMALLER HANDS: Every button stays within reach without stretching your fingers across the shell. Evoluent builds this same shape in more than one size, because a mouse that is too large for the hand on it undoes the posture it was built for.

WIRED USB, NOTHING TO CHARGE OR PAIR: Plug it in and it works. Basic button and wheel functions need no driver on any system that supports USB, so it is as welcome on a locked-down work machine as on your own.

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.

PRECISION OPTICAL SENSOR: Tracks accurately across a wide variety of surfaces, so it behaves the same on a bare desk, a cloth mat or a laminate top. High quality materials and workmanship throughout.

BUILT FOR THE HOURS, NOT THE MINUTES: Long spreadsheet days, CAD, photo and video editing, or an evening of gaming. Once you are on a mouse for six hours a day, the shape of it stops being a detail.

WHAT THE FIRST WEEK FEELS LIKE: Coming off a flat mouse takes a few days, and that is normal. Rest your hand on the shell instead of gripping it, keep the mouse close to the keyboard, and move from the elbow rather than the wrist.
