Logitech MX Ergo Wireless Trackball Mouse – Adjustable Ergonomic Design, control and Move Text/Images/Files Between 2 Windows and Apple Mac Computers (Bluetooth or USB), Rechargeable, Graphite

Comment

Ive been waiting for this device for well over a decade - a Bluetooth version of Logitechs fabled TrackMan Marble Wheel. And this is, indeed, a really nice trackball for use with new laptops that dont have USB-A ports, such as the MacBook/MacBook Pro. Im torn whether to give it four stars or five - its borderline, and if I could give 4.5, I would. I decided to round up. (And Ive gone back and forth several times while writing this review.) The trackball functionality is exactly as youd expect if you used the M570, with a few extra features - tiltable scrollwheel, the precision button to allow fine control, and the ability to switch between two devices. The AA battery has been replaced by li-poly and recharges via micro-USB. The form factor is where things get a little weird. The bottom of the trackball has a 20-degree bend in the middle, and magnets on either side. It ships with a 2mm-thick metal plate that can magnetically attach to either side to cause the tilt. The result feels much more stable than youd expect, and while you can deliberately tilt it, its not generally going to accidentally tilt when you arent expecting it. I find the tilt feels really good, actually - I hadnt expected it to. The downside of this is that it increases the weight by over 1/3, to over 9 ounces. The device is overall about 4 ounces heavier than the M570. You can use it without the metal plate, but it feels extremely wobbly in that state, and will fall to flat rather than tilted unless propped up. The only other issue is that theres no spot inside to hold the Unifying Receiver. Not an issue for me because I want this for Bluetooth, but may be an issue for someone. I purchased the MX Ergo Plus direct from Logitech - the difference is that the Plus ships with an additional plastic wedge that can add another 10 degrees of tilt. If that sounds useful to you, my understanding is that the Plus is exclusive to Logitech and Best Buy.

As an owner of 4 Logitech M570s (one for each laptop / desktop) I was really looking forward to the upgrade. Unfortunately, this doesnt feel like an upgrade at all. It requires new software (Replacing SetPoint with Logitech Options) which does NOT support the old "Pointer Acceleration" feature. Compared to the old M570 this is 4x the price with reduced functionality. Until they update the software I would NOT recommend it - especially if you are using a large multi-monitor setup. Other minor annoyances: 1) The trackball actually makes noise where the M570s are silent 2) Micro-USB connection where the rest of the world has moved to USB C 3) Far heavier than the M570 and a flatter profile.

I love Logitech mice. I still own the Performance MX which is a great video editing mouse, and I’ve always said that the M570 is one of the best ergonomic trackball mice. Now after 7 years, Logitech has finally released a new and improved wireless trackball which could easily become the best ergonomic mouse on the market. Logitech was nice enough to reach out and ask if I wanted to try an early test unit so here is my hands-on first look at the Logitech MX Ergo wireless trackball. In the box there’s the MX Ergo trackball mouse, a charging cable, a Logitech unifying receiver, and probably the most important piece, this magnetic metal hinge. This hinge snaps on to the bottom of the MX Ergo and lets you use the trackball at two different angles based on your own personal preference. This is definitely the best feature about this trackball in my opinion because the ability to switch between angles is great for improving wrist posture. The MX Ergo also claims to reduce muscular strain by 20% compared to a standard mouse. The overall design is excellent. It’s definitely made of high quality materials. It’s big enough and feels solid in my hand. The way it’s sculpted provides full support for the palm to rest on and scrolling isn’t awkward or tiring. The bulk of the mouse is made of a soft rubber which gives a nice comfortable grip. The bottom of the hinge has a good non-slip finish on it which helps the trackball stay in position when using it. It of course has left and right click buttons on top. The scroll wheel can not only scroll up and down, but it can also tilt for left and right scrolling, and it can also be pressed down to click. There’s an Easy-Switch button on top that lets you instantly switch between two computers without re-pairing, and you can also copy & paste data between the two computers with Logitech Flow. Both of these features require the free Logitech Options software. This software is not required to use the trackball, but it does give you more features and customization tools. The trackball itself has been smooth and accurate so far, and it doesn’t feel loose or anything. But for those of you who aren’t familiar with using a trackball, there is a convenient precision mode button near the ball so you can easily adjust the cursor speed and sensitivity allowing for faster and more precise control. The MX Ergo is compatible with the latest versions of Windows and Mac, and even though it comes with a USB unifying receiver that allows you to wirelessly connect up to six Logitech devices, the MX ergo does have built-in Bluetooth if you’d rather just use that instead of using the unifying receiver. It has a rechargeable battery inside that can potentially last up to four months on a full charge, depending on usage. But what’s really cool is that just one minute of charging usually gives enough charge for a day’s worth of work. That is super convenient for a wireless trackball. I gave it 4 out of 5 stars because I wish it had USB-C, and I wish it gave you the option to use it as a wired mouse instead of only wireless. That’s my first look a the MX Ergo. I’ve only had it for a few days, but so far I’m really impressed and it’s something that I will continue to use as my primary mouse when I’m not using my Apple Trackpad.

Ive been using the Logitech M570 exclusively for as long as I can remember. Currently I have 5 or 6 of the M570s lying around my house connected to various computers. Ive convinced my wife, co-workers and a few friends to switch to the M570. The M570 had one major drawback--no bluetooth connectivity. Like a lot of M570 fans, I was elated to read a couple months ago that Logitech was releasing a bluetooth version of this popular trackball. And then I actually used one. For me, the Ergo is uncomfortable to use. It is the first time using a Logitech trackball for 20 years that I felt any discomfort in my hand or wrist. This will likely vary by individual, but there are four flaws to the device that have led me to abandon it: 1. The metal riser on the MX Ergo increases the height of the device which results in awkward hand/thumb placement as compared to the M570. 2. The extra weight and the textured grip nature of the MX Ergo means that it has less "give" when you move your hand onto it. Rather than my hand gliding over the plastic of the M570 (especially when I am reaching to move the cursor without looking at the mouse directly *or* if Im readjusting my hand placement), the MX Ergo resists the movement of my hand. The result is something that I feel in my wrists after a few hours of use, and not in a good way. 3. The ball does not seem to roll as freely in the MX Ergo as it does in the M570. I used this for about a week before giving up on it. Four weeks later, I could still feel faint aching in my trapeziometacarpal joint. 4. As anyone who has owned an M570 knows, the ball needs to be removed periodically as dust, etc. will accumulate in the area that holds the ball. This is much more difficult to do in the MX Ergo. There is a hole underneath the ball, but it is not nearly big enough to fit a finger through. Youll need some sort of device small and strong enough to dislodge the ball, but also avoid scratching it. Really dumb design decision on Logitechs part. I have to wonder how much ergonomic testing of this they did, or if this is a quality control issue with these early units. Its a huge step backward from the M570 IMO.

This is about the sixth Logitech trackball Ive bought, along with half a dozen keyboards, and its among the best of their products. The M570 has been my favorite pointing device for years, and Ive worn out a couple of them -- the L and R button switches take a lot of beating, L especially, and after a couple years the button becomes erratic. This, of course, is a terrible flaw, since it means you may accidentally DROP something that youre dragging across the desktop -- occasionally into some folder you didnt notice -- and then its a challenge to find the file (or 100 files) you dropped. Logitech replaces these worn out trackballs for free, unless they last too long, and then Im stuck buying a replacement. But they last for years, and the M570 is now less than $25, so its not even $1/month "maintenance" cost. I mention the M570 reliability mainly because the new MX ERGO is reported to use button switches that are 10X longer-lived, or more. Since that was the only defect in the M570, that should mean the ERGO is pretty close to perfect. If it wears out in 20 years, I probably wont be around to care. Compared to the M570, the ERGO is heavier and I find it easier to keep in place on my desk. I love the sideways tilt feature, since I can use it lying flat for several hours, and then give my wrist some relief by switching to the more upright position, which allows the side of my hand to rest lightly on the desktop. Its also much easier to relax my fingers without inadvertently clicking L or R. I suppose if I were using this as a portable controller I might not like the extra weight, and I did often carry the M570 with me on trips. If I were doing that on a daily basis, in a briefcase or backpack, the added ounces and volume (the ERGO is about 20% larger) might be a problem. But the trade-off is that it stays put more easily, on a much larger and tackier rubber base layer, and its more restful to use. I do miss the acceleration feature, long a standard among mice and trackballs, but the one-touch Hi-Res button somewhat makes up for it. I would prefer both, and I hope Logitech will reinstate acceleration in the next update of the new configuration utility. The little nubs that the ball rides on are seemingly indestructible. Some reviewers complain that theyre plastic, but I believe theyre actually a kind of ceramic or glass. Considering that my oldest M570 (5 years?) still runs smoothly and the little nubs are still round with no visible flat spots, Id say theyre considerably harder than most plastics, and I doubt they are plastic at all. Viewed at 30X they look like ceramic to me -- glossy and absolutely smooth and spherical. In any case, they afford very light, smooth rotation in all directions, and they dont wear out. Like any small mechanism in a hands-on application, they do collect dust and other debris from ones hands, but that accumulation of dust and furch just makes the ball movement gradually increase in friction. Pop out the ball, flick of the little dust donuts with your fingernail, and the thing is super smooth and free-wheeling again. If I could take off half a star for the lack of acceleration, I might do so, but in all honesty, Ive been switching back and forth between an M570 and an ERGO for days now, and I cant say I notice any significant difference in pointer movement. On my 50" UHD monitor, its a long way from one side to the other, but thats why I use a trackball in the first place -- I can just swipe it a few times at the medium-high speed setting, and Ive traversed 3,840 horizontal pixels with barely any effort at all. In the end, if I had to trade the Hi-Res button for acceleration, Id go with the button, and of course thats what you get with the ERGO. But all this is really nit-picking. The biggest bonus after comfort is the improved scroll wheel, which now has L and R tilt, in addition to downward clicking, and Ive missed that for years using the M570. I do wish it had a few more buttons for less-frequent uses, but theres something to be said for simplicity -- I have a few other pointing devices with lots of buttons, and I was never able to make them indispensable. The biggest downside is the price. Im not sure why this costs 4X the price of an M570. Clearly its more expensive to manufacture, but not by that much, but then its new, and the development costs havent been amortized yet. If in a year or so it comes down to $39.95, Id call it a bargain.

Love it yet hate one thing... and it baffles me! OK - first the good - ive been a trackball user for almost 20 years..... I had to original model trackball from logitech and used both the wireless and wired versions. I never really thought about it, but the ergonomics on this are fantastic - it is definitely a more neutral and better position that is more comfortable. I also like the "precision mode". But here are my two gripes.... 1) I bought this specifically for the Bluetooth functionality..... it seems quirky... once it "goes to sleep" it lags a minute before getting going and last night it started acting flaky.... never had that with my other trackballs.... i dont want to use the unifying reciever because i need all my USB ports. 2) and this is the one that baffles me.... in order to provide the ergonomic "pivot plate" they use a VERY STRONG MAGNET! How did i figure this out? I have a large laptop with a numeric keypad and metal case - the trackball fits perfectly below the keypad it, next to the trackpad..... i set it there like i have always done and worked for a bit, then i went to take it off and to my horror, it was stuck to the laptop! Thank goodness i have an SSD and not a magnetic hard drive! LOGITECH - why in the world would you put a huge magnet on a device being used around computers???!!! Really dumb engineering move!

Compared to the m570 you pay four times as much and get a hinge that adds a ton of weight and attaches with a magnet(and if you lose it the mouse doesn’t sit right), Bluetooth integration, sideways scroll, some extra buttons, and the privilege of using the new Logitech options software that has fewer options than the old setpoint software. Notably missing is the option for pointer acceleration, which is critical for trackball usability. It’s also much more difficult to pop the trackball for cleaning. I was very excited to receive this item but as soon as I started using it I found myself asking why I paid so much more for one step forward and two steps backward. You’re better off buying an m570 and making a wedge with a small doorstop and some stick on Velcro.

Received the ERGO trackball this morning. Was very much looking forward to it, given that (like many others) the M570 was one of my favorite Logitech mice. So, I put the MX ERGO in service immediately. My first impressions are …. hhhmmmm, not what I had hoped for. For my rather small hands, the trackball doesn’t feel comfortable if I’m to operate all controls. My hand doesn’t rest ‘naturally’ on the mouse (at any ‘variable’ tilt angle.) The trackball is too bulky. And, let’s face it; the trackball feature of this mouse, i.e. the prevention of wrist strains, is really the main attraction for the M570 / MX ERGO aficionados. In that category, the MX ERGO, in my initial (i.e. 3-4 hour) impression, barely gets a passing grade. As to the additional features, i.e. the sideways 20˚ tilt function and optional / pointer settings, I have yet to explore the full range. The mouse / pointer responds accurately and well, as do most Logitech wireless mice. Adjustments are easy to initiate and adaptable with necessary, respectively preferable precision. No complaint there. Generally, Logitech Options, the software app controlling the MX ERGO (and other Logitech hardware) is self-explanatory. I’m not awestruck by what I had anticipated would be (or should be) an amazing, state-of-the-art, innovative (functionally) trackball at a price of $99.00. I second other opinions that in comparison to the M570, this mouse is way too expensive for what seem, initially, to be limited improvements. At $99.00, the price is absurd. Around a $50.00 price level, the amount would be acceptable (given the “imagined” technological advances incorporated in the MX ERGO.) I have not yet made up my mind whether to test the MX ERGO for a short while longer or to return it (even at a small loss.) What was to be an exciting event (for me), proved to be a deflating balloon. Update: 11.10.2017 - Returned the MX ERGO.

Bought one as soon as it was announced, and boy was I disappointed. The left button didnt click straight out of the package, and after some gentle tapping, I got it to at least click. However, the button is sticky, which means unless I did a very quick tap, the button would stay down after I lifted my finger. Since the left button is the primary one, this was a deal breaker. The ball also rolled poorly, which is a comical regression compared to all previous products from Logitech. A trackball has two primary requirements: a ball that rolls and a button that clicks. This $99 piece of junk failed both. This is the first trackball I have returned after 20+ years of using them.

Flaw: There were other reviews about "misclicks" - I feel this is what they were talking about. The copy of the mouse I got is prone to having the click in the pointer finger "stick". Not due to it sticking, but lacking a "bounce back" or recoil. In fact, there was a noticeable difference in the right, middle-finger clickpad, which was sharp and the responsive, and the left (pointer), that sinks in. I have to consciously attempt to raise my finger - like *lift* the finger from the mouse. Compared to a g400s, which has a great click pad to it thats reliable, I can repeatedly click rapidly and my finger never leaves the surface. The MX ERGO will let your finger drag and sit. This is critical if you intend on doing any gaming. And I gamed fine with the MX570. OK: Im on a 4k monitor and itd be nice if there were more ways to toggle sensitivity. At the moment, there was only a very precise sensitivity, and one that didnt perform as well on a huge monitor. I had to adjust it through the software. Pros: - The quality of the hardware is excellent, despite the click - The accuracy of the ball/laser is excellent. - The scroll wheel in the middle is also fluid and accurate. - The right-click is great.
