A Genuine Left-Handed Vertical Mouse for Medium to Large Hands
The Evoluent VML4 is the left-handed version of Evoluent's established VerticalMouse 4, with the entire body, thumb support and button layout shaped specifically around the left hand.
Its upright, handshake-style design supports the hand in a more vertical orientation than a conventional flat mouse, reducing the amount of forearm rotation required to place the palm towards the desk.
Designed for medium to large left hands, it combines a sculpted full-hand shape with six controls, adjustable pointer speed and reliable wired USB connectivity.
Not an ambidextrous mouse turned around — this one is shaped specifically for the left hand.
The thumb support sits on the right side of the mouse while the primary finger controls sit on the left, creating a true mirror-image layout for left-handed users.
Built Specifically for Left-Handed Mousing
True Left-Handed Shape
The VM4L is a mirror-image left-handed design with dedicated thumb support and controls positioned around the natural grip of the left hand.
Handshake-Style Position
The vertical body supports a more upright hand orientation, reducing the amount the forearm needs to rotate towards a palm-down position.
Six Mouse Controls
Dedicated finger and thumb controls provide everyday clicking, scrolling and navigation functions directly from the mouse.
Hardware Pointer-Speed Control
Change between four pointer-speed levels directly from the mouse, with illuminated indicators showing the selected setting.
Why Use a Vertical Mouse?
With a conventional flat mouse, the forearm rotates inwards so the palm faces down towards the desk.
The Evoluent VML4 turns the mouse body onto a more upright orientation, allowing the hand to approach it in a position closer to a handshake.
The sculpted body then supports the fingers, palm and thumb around the mouse so you can control it without relying on a flat, palm-down grip.
Best Suited to Medium and Large Left Hands
Evoluent recommends the regular VerticalMouse 4 Left for hands measuring approximately 178mm or longer from the wrist crease to the tip of the middle finger.
Its full-size sculpted body gives the palm, fingers and thumb substantial contact with the mouse, making hand size an important part of selecting the right model.
Controls Positioned Around the Fingers and Thumb
The VM4L provides six controls with default functions including primary click, secondary click, middle click, forward, back and scrolling.
The main finger controls sit beneath the fingers while two additional buttons are positioned around the thumb area, allowing common navigation functions without repeatedly returning to the keyboard.
Evoluent also uses an optical scroll-wheel mechanism designed for smooth, durable operation.
Change Pointer Speed Directly from the Mouse
A dedicated pointer-speed control lets you switch between four hardware sensitivity levels without opening your computer's mouse settings.
Illuminated indicators show the current level, making it easy to use a slower setting for precise cursor work or a faster setting when moving across larger displays.
Plug In and Use It — Then Customise Further on Windows
The Evoluent VML4 works as a standard USB mouse without needing additional software for normal clicking and scrolling.
Windows users can optionally install Evoluent Mouse Manager to customise button functions, assign keyboard shortcuts and configure different commands for different applications.
Using macOS? Core mouse functions are supported, but Evoluent Mouse Manager is currently Windows-only. Button functions therefore remain fixed on macOS unless compatible third-party software is used.
Reliable Wired USB Connection
The VM4L connects through a USB Type-A cable approximately 2.1 metres long.
That makes it a straightforward option for permanent office workstations: no pairing, receiver management, batteries or charging required.
Computers equipped only with USB-C ports will require a suitable USB-A to USB-C adapter or hub.
Sculpted Full-Hand Support
At approximately 8.9cm wide × 11.1cm long × 8cm high, the VML4 has a substantial vertical body designed to support a medium-to-large hand.
A thumb rest and lower finger flange help give the thumb and smaller fingers dedicated support around the sides of the mouse rather than leaving them unsupported against the desk.
