3M Ergonomic Mouse - 3M Ergonomic Mouse

Our Score:


The Ergo Mouse's precise control was also not helped by it's poor tracking abilities. Whether it was the sensor (we suspect it is, as it's just optical as opposed to laser) or some signalling problem, we're not sure, but every now and then the cursor will just stop responding or become slow and jittery in its movement. Like the speed of movement issue, this will probably be a minor problem to slower computer users but if you're used to interacting with your computer quickly without having to think about it, it will be a major annoyance. It's also not the smoothest mouse to slide around thanks to some very small glidepads.

Further problems stem from the lack of a scroll wheel and general dearth of buttons. This mouse does have the essentials in the form of a rocker button, which sits under your thumb and acts as your traditional left and right buttons, and a large button that runs down the front of the joystick that emulates the middle button (normally used for scrolling). But without a scroll wheel for small and quick scroll movements or forward and back buttons for traversing pages in a web browser, overall navigation can feel limited. Of course, we can see the logic that more buttons, and particularly a scroll wheel, could make the Ergo Mouse more difficult to use and possibly even counter its benefits, but to have such a lack of functionality is going to be a major problem for any serious PC users.

As for other features, the Ergo Mouse is available in two versions: Large (EM550GPL) - which we're reviewing here - and Small/Medium (EM550GPS). It's a wireless device, too, so if clutter is a concern that's a plus point. It also seems well built with a sturdy, solid feel and a smooth, soft-touch finish all over. On the underside is a battery compartment, an On/Off switch, and a button for syncing the mouse with its included USB receiver. Two AAAs are needed and some basic ones are provided in the box.

Comparing the Ergo Mouse to alternative RSI reducing mice, it's definitely a difficult one to call. While sculpted conventional mice like the Microsoft Natural 6000 provide better tracking and have more functions, they still aren't quite as comfortable as the joystick design. Trackballs are also a possibility and again can offer better accuracy and more functions but can be uncomfortable as well. However, generalities aside, this particular 3M Ergonomic Mouse just doesn't quite cut it. The tracking isn't good enough, it has too few functions, motion isn't smooth enough, and it's just a bit too expensive.


The 3M Ergonomic Mouse is one of the most effective anti-RSI pointing devices we've seen. Its design ensures your wrist and arm are in their most comfortable position and the button arrangement is also very comfortable. However, its tracking isn't great, it's slow to use, and even though you should put your health above all else, we think it's a bit too expensive – just get up and take a break regularly.

I had to use a computer today where this mouse was connected.. wtf!


In all seriousness if you sit at a desk for a long time just buy decent peripherals and spend a few minutes reading how you should adjust your chair and monitor, RSI isn't all that fun.

This is a blast from the past, this was originally launched in 2001 or so, I guess the wireless edition is new and what prompted the review?

I tried the 3M mouse a while ago and didn't get on with it - I found it impossible to use accurately. The Evoluent vertical mouse was a better solution for me and has dramatically reduced the pain I experience in my right arm. Yes, it is a bit of a 'WTF' experience when you first use it but it's well worth the effort of adapting. Ergonomic positioning can only go so far - the traditional mouse is a fundamentally un-ergonomic device - and it's a shame more manufacturers aren't adopting more radically alternative designs.

@Xiphias: Yeah, it's a new revision.

I've recently noticed that 3M has a very big presence in technology. For instance, at my university library, they make the security scanners, the library return system, the cash top-up counters, library checkout system. Everything!

I have RSI in my wrist and this is the best mice I have come across - for my wrist. Agreed, it is difficult to accurately position until you turn the mouse travel speed down and accept that you have to use your arm more. Then, it becomes very easy. The main bugbear is the apparent "crashing" of the mouse. Unless you keep the thing permanently moving around, it stops tracking for the first few inches of movement. I wonder whether the cable version behaves better (my friend has one which she says is fine) or whether this is something wrong with the newer models. Overall though, I will happily get frustrated with some minor niggles rather that suffer pain - and make my wrist even worse.

After getting starting to get some signs of RSI, I started using these several years ago (non-wireless), and haven't had any trouble since, apart from some jokes about the look of it at work.

You do quickly get used to it, but it probably isn't quite as accurate as a good quality mouse.

The base lifts your hand off the table by about 1cm, so you need to rest your arm on something about the same height, otherwise it can get uncomfortable.

I used to have RSI too, and now I totally swear by my Microsoft Natural Ergonomic Laser Mouse 6000. It might have the longest title for a mouse, but it's completely removed the pain I was suffering in my wrist and tendons along the top of my hand. I can recommend the corresponding keyboard too. Also, my wife had exactly the same problems, and we fixed her up with the same mouse and keyboard and her pain's gone too.

"Most obviously, due to the way in which you hold the Ergo Mouse, you have to use your whole arm to move it, making it difficult to use accurately."

That sounds like you normally rest your wrist on the desk when using a normal mouse. One of the ways that I've reduced wrist pain is to avoid resting my arm on anything. It takes a bit of getting used to but is made easier by organising your setup so that the mouse is as close to your body as possible, i.e. definitely *not* to the right of a full-size kwyboard's number pad.

Anyone with answers would be greatly appreciated,

I'm using the 3M ergo mouse, but cannot enable the middle button to scroll on an "all applications" basis. I cannot scroll in any application except for ADOBE... what gives? Shouldn't this be universal across all apps?

Im am using a brand new macbook air with the most updated IOS. In my system preferences, there is no option for the middle button, just the left and right. I've been looking all over for drivers, but can't figure out what to do. I've even emailed into the 3M website for support and am waiting to hear back.

Please let me know how I can enable scrolling. I really like this mouse, but the lack of scroll is going to be a deal breaker pretty soon.

MouseTrapper Advance mouse is an ergonomic mouse, the relief of pain and repetitive
stress injuries associated
with mouse clicking and typing it’s easy to use great innovation

You can scroll with the 3M by holding the 3rd button (under your fingertips) and moving the mouse up or down.
