Customer Ratings & Reviews

Well built., takes some getting use to . So I use it when I don’t want to move a mouse around due to limited desk space.

Horrible design, cant get comfortable with it. not designed for road warriors. Wouldn't buy another one. And I have loved my logitech trackballs over the years. I'm going back to the older version; much better product at a much lower price

This is only my second trackball. Haven’t used one in many years. Things have really changed. This is a state of the art product with too many features to mention here. This trackball can be used on Bluetooth or via a Unifying Receiver plugged into a USB port. It can be used with two computers at the same time. U press a button to switch between them. Believe this requires installation of optional software from the Logitech website. The battery is rechargeable via a USB port and good for four months. Charge it for only one minute to last a full day. Please be aware that I am now using this product on an Acer R11 Chromebook. Have the Unifying Receiver plugged into a USB 2.0 port. I also paired it using Bluetooth to an Acer Iconia 10.1” Android tablet running Android 5.1 Optional software probably won’t work on Chrome OS or Android but I don’t really need it. YMMV. Specs say Windows and Mac OSX is only supported. So now U know. Looking forward to less hand strain and the ability to use this fine product on a smaller desktop footprint. And not worrying about battery life or having to keep spare batteries stocked. Another win Logitech. Well done !!

I genuinely don't like giving hardware recommendations, especially if they're more expensive than what I'm used to. But after having had one for about 2 years, I have to say that this thing has actually made a real difference for my carpal tunnel. It's 100 bucks, which is annoying to spend for a mouse. And it's Logitech, which means that the button switches WILL die in about 2 years, give or take. That said, that extra tilt on the thing has made a noticeable difference in my pain levels. Also, it doesn't need batteries - plug it in via USB for about 10 minutes, and that'll run it for at least a month, if not longer. With the app they have and the unifying receivers, was as easy as clicking a button, switching one off and the other one on. So that's also a good thing.

I've been a fan of trackballs for years. I like their comfort, and I like that they use such a small footprint on your workspace. Unfortunately, trackballs haven't liked me back. Over the years, they'd had all sorts of design limitations, mostly poor and unreliable tracking, no precision. This trackball solves these issues and more! At first I was going to use it to replace my desktop setup. Now I think it's going to be my primary mouse for travel and everything! It's cordless. It uses Bluetooth so you aren't dependent on the usb receiver. This means it's easy to share among two computers because you can switch between channels, you don't have to take the receiver with you, and you get to conserve a precious USB port, and the battery life is impressive so far. The pointer tracking is awesome. It is as responsive as a top grade mouse, and you don't have to pick up and reposition your thumb to move the pointer across your screen. It even has a precision mode; just hit the button above the ball and suddenly the ball moves the pointer precisely over a small space. The adjustable angle -- really clever engineering. At first I was really leery of it. The bases are attached by magnet, so I thought it would be a hassle to stow the mouse in my bag, and that it wouldn't support the weight of my hand when I'm excitedly zipping around the screen. It's really stabile, even at the extreme maximum angle. By the way, that extreme angle is really comfortable for me and my big hands, it feels way better than the traditional shallow position of a trackball. It has the minimum buttons I've grown to need these days -- it has a scroll wheel and forward and back buttons. I'm not happy with the position of the forward and back buttons, and that cost the review one whole star. Forward and back should be at opposite sides of the trackball so they are more intuitive and I can hit them without repositioning my index finger. That's a big departure from what I'm used to. Also, the stacked orientation of the forward and back buttons is not intuitive, so I have to consciously think about which is which. The scroll wheel is pretty good. One improvement would be a quick way to scroll to the top or bottom of the window. I never quite got used to tilting the scroll wheel for side scrolling. I recently got a Logitech MX Master 2S mouse, and it has a side scroll wheel right under your thumb. That would be awesome for this trackball. I would position it on the edge of the device, near where the precision button is located. Overall, if you're a trackball fan, get this one.

Like the mouse but the thumb button gets triggered often when you don’t mean to do it and the tilt side to side is awkward and tilts when you don’t mean to do it.

Left button doesn't work properly, it seems to be stuck in the pressed position.

I cpuldn't get used to the ergonomics. Not a good fit for me

It is satisfactory but it is been years since last update to the model.

I have to say. I don't usually use trackballs. They don't feel natural in the hand, but Logitech did an amazing job with this one. This trackball feels great in the hand. The form factor may be awkward to some people, but I honestly thought that is what separated it from the others. With the use of a metal magnetic piece that functions as an hinge, you can tilt the mouse 20 degrees. Add the wedge in for another 10 degree tilt for a 30 degree tilt. I personally felt the 20 degrees felt more natural, but to each their own. The tilt feels really good and stable. I don't foresee any accidental tilts. I really like the 20 degree tilt, but you can definitely just stick with zero tilt. The metal magnetic piece makes the mouse a bit heavier, but I personally liked having a little more heft to keep it stationary. You can do without the metal piece, but it feels really light, cheap, and unstable. It doesn't stay in the tilted position all too well so definitely need that metal piece. The bluetooth function is great. You can switch between 2 devices. For me, I have a desktop and a Macbook Pro so it's great that I can switch between them. Also, given that the new Macbooks don't have USB-A ports, it allows me to use an actual mouse without the use of an adapter. The scroll is amazing. I find it to be really smooth. The trackball is really smooth as you would expect from a good mouse. It is a rechargeable battery, which is great. I don't need to keep buying batteries to power the thing. There are some critiques that I have: I didn't really find a use for what they called "precision" mode. Which is when you press the button to allow for finer control. Other people may find a use for it although a layperson like me did fine without it. I think this is a problem with alot of Logitech products, but I really get annoyed when there is no spot to hold the unifying receivers. I have lost so many of them. Granted, I mainly use this as a bluetooth mouse so it wasn't too much of a bother. All in all, great comfortable mouse that is my daily driver.

I had the mouse for a month and 5 days and it stopped working. Of course, it was not returnable!

Lived on a desk for a year, and 5 months. The buttons still work, but trackball is dead.

Did not like it at all. Removing the battery needs to be easier.

IT RAN OUT OF BATTERY IN A MONTH. IT RAN OUT OF BATTERY IN A MONTH.

I love this mouse. I’m not a fan of short mice as I like to stretch my hand out while using them (short one at work drives me nuts!). I’m able to lay most of my hand on the mouse comfortably and it fits to the curvature of my hand nicely. Each of the 7 buttons (standard L/R mouse, scroll wheel with three directions plus scrolling, forward, back, precision mode, and option buttons) are easily accessible. This is advertised as having “a scroll wheel and 8 buttons” but, from what I can gather, they’re considering the ball and on/off switch (located on the bottom) buttons. I wouldn’t. There are two angles (0*, 10*) built in to the base plate plus an angled pad raising the mouse to 20*. I found the 10* angle to be most comfortable for me but each person is different. It’s great to have options. For long nights I have used this on a MacBook Pro, a Dell XPS with Win10, and a home made desktop running Ubuntu 17.10. All were plug & play without issue. I’ve used a couple trackballs in the past so I’m comfortable, but this mouse is considerably larger. I haven’t taken the opportunity to play games with this one yet. Since it takes some getting use to, I’d be cautious with games until it’s more natural. User preference. I have no negative remarks. I’ve never used a mouse this comfortable and with this much versatility before. It’s very comfortable, makes web-browsing, Visio modifications, and even excel documents easier to manage. I would definitely recommend this to a friend and I already have. Way to go Logitech on a job well done.

Dont like how it rocks back and forth. Plugging in is a pain. Like the cheaper model better.

I'm using this with an iMac with which I was previously using a Magic Trackpad. I haven't used a trackball in years and have to say that I'm not only very impressed with the ergonomic flexibility of this Logi but also the endless customization options for the buttons and scroll wheel. When you first open the package, you're instructed to d/l the Logi software to your computer and then decide if you're going to connect the Logi via your computer's built-in bluetooth or via the included USB dongle. I just went the bluetooth route and connection was seamless. Then, you are presented with options to configure your Logi with the default settings or customize every button, scroll wheel and trackball. There are so many options - it's almost fun to see what each option does. And, it's pretty neat how you can *almost* recreate the multitouch swipe gestures of the Magic Trackpad by using the buttons and scroll wheel on the Logi. In terms of ergonomics, there are basically three options for how you want the Logi to sit on your desk - 0, 20 or 30 degree angles. This was the only area where I found the instructions on how to adjust the ergonomics a bit confusing. There's a short animation in the software, but I found the picture on the back of the box most helpful. If you are interested in something to decrease or prevent wrist pain and have an amazing array of options to customize, then I would highly recommend this Logi.

Its pricey but definitely worth it if you like trackball mice. I've been using the M570 for years and had the clicking issue with the microswitches. This one feels very rugged and heavy which is good. Feels very ergonomic. It can be paired to 2 different devices and can be switched back and forth. Uses Bluetooth or the usb dongle which is included.

Waste of money. Doesn't work. Will return next time I go to store.

Logitech has created a mouse for better wrist posture and pronation. They were able to accomplish this by adding an adjustable hinge. This hinge is great, it allows you to tilt the mouse to an angle that is more comfortable for your hand, wrist, elbow and shoulder which will all help your neck. The hinge let’s you tilt the mouse from 0-30 degrees to best fit you. The larger surface area lets you rest your entire palm on the mouse instead of just a portion, which makes it easy to click the left and right buttons and in flicking across the trackball. The MX ergo has Logitech’s typical customization and I really liked the pointer precision mode which the trackball extremely precise. What made the precision mode work so well was that it slows down the pointer speed making it easier to control the trackball. The MX Ergo quickly switched between different devices and you won’t have to repair the mouse when you switch the mouse over to a different computer. The only person I would not recommend this mouse for is for small hands such as a child, but other wise it is great, especially if you use your mouse a lot while on your computer.
