## Overview

The Evoluent VM4L is the pioneering left-handed ergonomic vertical mouse designed to eliminate forearm twisting and wrist strain. Featuring a sculpted handshake posture, six customizable buttons, and four adjustable pointer speeds, it offers plug-and-play wired USB connectivity compatible with Windows, Mac, and Linux. Built for professionals who demand comfort during long hours, its precision optical sensor tracks smoothly across surfaces, while its unique design supports natural hand positioning proven to reduce repetitive strain injuries.

## Description

Avoids forearm twisting for comfort and good health. The patented shape supports your hand in an upright neutral posture that generally avoids forearm twisting. Many users, including medical doctors, ergonomists and physical therapists, said the Evoluent VerticalMouse provides superior comfort and even relieved their wrist pain.

Review: A no-compromise left-handed ergonomic mouse - I like this mouse better than the Logitech MX 610 Left-Hand Laser Cordless Mouse , which it replaced. The unusual sideways orientation of the Evoluent looks strange, but it took no time getting used to. It promotes a very relaxed and natural hand and wrist posture. It looks like your fingers are lined up vertically, but in reality, your fingers are positioned in a gentle arc and your hand is turned inwards by a few degrees. Your thumb rests in a chrome-looking divot. The Evoluent 4 design has a bottom "lip" that prevents your pinky finger from rubbing against the desk. I can confirm that it works beautifully and adds to the overall comfort. It helps you to position your hand correctly. I also find that proper chair height (in relation to your desk) and wrist support is essential to keeping the arm and wrist straight. It also has a very long cord, approximately 6 ft. Your index, middle, and ring fingers align with buttons 1, 2 and 3. Between buttons 1 and 2 are a scroll wheel (with notched movement). The scroll wheel can be clicked as another button. Above and below the thumb are two additional buttons that could be used for back/forward functions in your favorite browser, bringing the total button count to 6, and they are all programmable under Windows (a non-WQHL-certified 32-bit and 64-bit Windows driver are included in the box on a small (mini) CD. The purpose of the drivers is to assign custom actions for the buttons. You can even assign actions to a combination of the thumb and finger buttons when pressed simultaneously. Mouse sensitivity is controlled by its own dedicated rocker buttons located where it cannot be accidentally pressed. Note: Even though the Evoluent Windows drivers warns you to uninstall any previous mouse drivers to "prevent conflicts," I ignored that and kept my Logitech drivers (SetPoint). Both mice work fine. I can actually still access the SetPoint drivers through a tab in the Evoluent drivers setting page. Nice. The Evoluent's sensitivity is indicated by 4 LEDs located at the top of the thumb divot and correspond to four hard-wired sensitivity settings. The lowest sensitivity is around 400cpi, while the highest feels like around 2000cpi (these are my estimates obtained by comparing it with other mice; it is not specified by Evoluent). I operate it on the 2nd-lowest setting, which is about 800cpi. The nice thing is that the sensitivity function does not require special OS drivers, so it works right out of the box on any computer and any OS. The mouse even remembers the last sensitivity setting used when you unplug it. The sensor is an eye-safe infrared laser. Even though it is not sold as a "gaming mouse", the Evoluent 4's sensor performs as well as gaming mice in both speed and tracking under high-acceleration. That is more than I can say for the MX 610. There are no Mac OS drivers supplied by the company, although third-party drivers exist for reprogramming the buttons (links are provided on the Evoluent product page). On Mac OS X, I did not install the third-party drivers, so I could not assign any special functions for the buttons. Out of the box, the button under your index finger is mapped to the "left button" (primary on a right-handed mouse). Button 3 under your ring finger is mapped to the "right button" (secondary). Button 2 (middle finger) brings up the Mac OS X dashboard, and the top thumb button triggers Exposé. The bottom thumb button and the mouse wheel button do nothing. The mouse is light enough and sensitive enough to push around with just your wrist; you don't have to move your whole arm. You can even steer it with just your thumb and finger tips. This is the secret to its comfort. It encourages you not to grip the mouse with any tension. You don't need to. With conventional mice, even ergonomic ones like the Logitech, I eventually find myself gripping the mouse with just the ring finger and thumb, and that creates tension and fatigue within an hour of use. The downsides are minor. The buttons don't require much force to click. While I like the light touch, it's sensitive enough that just reaching out and wrapping my hand around the mouse will sometimes result in unwanted button clicks. This is not a big problem, but I have noticed a minor increase in accidental clicking since I began using the Evoluent. Maybe I am still getting used to it. I can pick up and reposition the mouse while resting my fingers on the buttons without clicking those buttons, so it is not hair-trigger sensitive. Also, the dark gray part of the mouse where your palm touches is covered in a "soft touch" coating. While it feels nice, this type of coating is not very durable in the long run and will start to breakdown after several years, becoming tacky to the touch, or it can rub off at the points of frequent contact. This is probably why the pamphlet in the box warns not to use solvents or cleaners on the mouse, only a damp cloth. I wish companies would stop using this coating. Its unusual appearance also makes it a great conversation piece. Bottom line: if you're thinking about buying this mouse, buy it!
Review: Eliminated awful pain! - Seriously, these mice have LITERALLY - LIT. ER. ALL. Y. changed my pain levels. I have Lupus, but before that, I had 3 surgeries total between both wrists. Carpal tunnel and De Quervain's. I started hobbying in carpentry about 10 yrs ago. It only took about 3 yrs before I had troubles. I never thought I'd love such an expensive, frustrating hobby so much but I do. Healing from those surgeries made me realize it's a vital piece of my mental well-being. Buuut I also have to go to work and be an accountant. Before I could do THAT, I had to go to school for 5 years. Do you see where I'm going with this? So 5 years pursuing my degree, where colleges are still using furniture from the 70s. To be fair, it's 2026 and we STILL manufacture desks and chairs so your arms go numb, so I guess I can't be too hard on the 70s, huh? I invested a lot in my ergo needs - a really expensive keyboard that looks like it's from outer space, custom made chair from - you'll love this - the 70s. Ha! Revamped it to suit my needs. Standing desk, a tiered foot stool for a leg-up on different levels, AND an ergo mouse. Or, mice. Because I swear I've bought them all. The muscle belly in my right forearm would BURRRRN. And I mean the kind of burning where it feels like there's a lighter under your skin. The kind where you wanna claw it off to escape your own body. Feels like ice and gives you goosebumps it hurts so bad. And I did PT for a yr with the max amt of the electro whatever things they had me wear afterward for like 2 hrs. I had multiple injections to no avail. Changed mice, to NO avail. I researched my brains out to figure this out and I have to take a sec to digress here - who is shaking hands at the angle these mice are allegedly manufactured for?! Seriously!! "Handshake" position - what?! I shake hands up and down, not at some wonky 30° angle or whatever the "norm" is for all the other mice on the market! Shake someone's hand right now. Seriously, do it. Is your palm facing OUT, or out and DOWN? If it isn't the first one, you need to go figure your life out. You gonna navigate a mouse in that position all day every day for 50 yrs?! Good luck with that. I have been using my left hand dominantly for certain things, for about 6 years. I can write numbers really well, programmed my keyboard for a left 10-key and became efficient on that years ago, and I do a lot of operating my power tools left-handed. Therefore, I got 2 of these. A right and left. I wish the left were cordless, but it wasn't worth not having the option just because it was corded. It has been about 6 months. I use both mice equally in my day. I navigate from my elbow or shoulder, NOT my wrist. These mice are absolutely WONDERFUL. Just...no words. The muscle belly in my right forearm has only flared up ONE. TIME. And it was NOTHING like it used to. And to clarify, this was previously happening every. Single. Day. Almost every second I was using a mouse, for YEARS. Let THAT sink in if you're still hesitating. I have them both at work, and in my career, I attend conferences out of town, meetings where I take minutes - I tote my whole setup. These mice are bulky - idc. They go with me. It doesn't matter if I only needed to use a mouse for 5 mins. I have already experienced repeatedly that I can no longer navigate a computer for even that amt of time, using a regular mouse or mouse pad, without severe burning. These things are so comfortable, I can easily navigate from my elbow because their bulk allows me to actually rest my wrist WITHOUT DRAGGING IT ON THE DESK! No one is making mice like this you guys! Your wrist isn't elevated with those other products - I was looking at stupid arm thingies that clamp to your desk so the skin on my arm could quit going numb from rubbing all over the desk! When you have problems, you can't rest your wrist on a pad and navigate FROM the wrist. That's probably how you GOT the problems to begin with because we AREN'T supposed to be DOING that. AND, if you really just sit in a resting position with your alleged ergo mouse, your wrist is PRObably slightly tilted UP. WRONG IDEA, mouse-making people!! This dude - he's a flipping genius. I am SO glad he didn't give up when everyone told him this was a stupid idea because people like me would be seriously screwed. Do. Not. Hesitate. I looked EVERYWHERE. Spent hours and hours reading reviews, omG did I ever. This mouse is it. It has literally solved a HUGE threat to my career longevity.

## Features

- UPRIGHT HANDSHAKE POSTURE: The VM4L 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.
- SCULPTED FOR THE LEFT HAND, NOT FLIPPED: This is not a symmetrical mouse turned around. The thumb rest, the button layout and the lower lip are all mirrored, so a left hand gets the fit a right hand has always had.
- 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.

### ⭐⭐⭐⭐ Great Mouse With One Very Minor Design Flaw
*by E***Z on December 11, 2023*

I purchased the left-handed Evoluent VM4L VerticalMouse 4 (wired) and I am loving it so far! The footprint is a bit wider than a standard mouse and I have a limited mousing area due to my keyboard tray but it still works fine. My first day using it, I lost count of the number of times I knocked it off of my desk because of its height! A standard mouse, you just shift your hand to the left and mouse on. With this mouse, your hand has to go slightly UP and over to the left to get your mouse on haha. By the end of the day though it was burned into my muscle memory. One minor design flaw that I noticed: the pinky button extends all the way to the bottom lip of the mouse and if I could get a dollar for each accidental click this mouse would have been free. In my opinion, the pinky button should be cut ABOVE the lip to avoid accidental clicks. I had to disable the pinky button because of this, and it is now useless to me. I also noticed that I have to press down firmly (again, using my pinky finger to anchor on the bottom lip) to get precision mousing. I've tried pressing my thumb firmly against the thumb rest for precision mousing but that didn't work out too well. I also tried changing the pointer speed but it boils down to having to apply slight downward pressure for accurate mousing. I'm thinking of buying the Logitech left-handed mouse as a point of comparison. Despite these minor issues, this is a really great mouse and it has helped relieve my finger pain.
