Customer Ratings & Reviews

After having carpal tunnel surgery, I needed to find truly ergonomic products. This mouse has been an absolute game-changer. It's so good that I now own three of them—for work, home, and travel! The trackball is incredibly responsive and the customization options are perfect. Whether I'm working or gaming, this mouse allows me to be highly productive with minimal hand movement, which has made a world of difference. Highly recommended!

I would give this 5 stars, however, after using this mouse for a while now, I've noticed that left click button doesn't work always. This is especially true when trying to highlight a word by double clicking. Instead I need to scroll over the whole word using the track ball. It's a nuisance. Still, I do enjoy many aspects of this mouse: the way it feels in my hand, the long-lasting battery, and the fact that it is rechargeable. These are all great features. It's also very comfortable. If you have pain in your wrist from using more conventional mice, I would recommend this mouse. That being said, if proper ergonomics is your main goal, I'm sure there are cheaper ones available that will have a similar effect.

My wrist huts using normal mice and I have been using these thumb trackballs for around 15 years. Logitech makes the most comfortable trackballs. That said. The only reason I went with this option over the cheaper one with the dongle is that this one has bluetooth. Current generation laptops don't have full sized USB ports so the M575 is no longer viable in 2025. Frankly I do not like the new design compared to the M575. This one is much heavier and has a heavy metal plate with a magnetic tilting thing that I suppose makes it possible to be more ergonomic for some people but unfortunately makes it much heavier. The buttons also seem to wear out in about 1.5 years guaranteeing you will need to buy a new one. The old ones with the USB cables still work fine so at some point they must have started getting lower quality switches. The M575 was much lighter and easier to carry around in laptop bad. This model is very heavy and the magnetic solid steel plate on the bottom makes it rather painful if you drop the mouse on your bare foot. The price is also verry high compared to the M575. You can commonly fine the M575 for $40 while this model is going to cost you a minimum of $80 depending on if you catch a sale. The button next to the mouse wheel is also a bit annoying activating a slowmo mode.

I love how smooth the mouse is. The ball rolls smoothly and doesn't seem to hesitate. The range from where it plugs in to the computer and the mouse is much greater than the others I have had

Fantastic for someone who has any wrist pain from using a normal mouse. The different levels of angles lets you adjust to your most comfortable fit. Extra keys can be configured for custom actions

This is one of the best ergonomic mice I’ve ever owned. The extra tilt makes it incredibly comfortable for extended use.

Nice features and is easy to use. It's accurate as well. A little expensive but worth it imo.

Really good mouse, responsive, maybe a little too easybto gonibto precision mode if you have a wild thumb, but overall worth the updrage from the lower model imo. My hand like the higher angle, my brain likes the multiple angle options

This mouse has BALLZ! I love trackballs for long game sessions so I don't get wrist fatigue from sliding a mouse all over the place. Logitech also has a suite of controls you can download to set the speed, angle, sensitivity, acceleration, etc. to customize it to your play style. I set mine so moving my thumb gently from one side to the other is the exact distance to move the mouse cursor across the screen so i never have to lift my thumb unless i need to switch to precision mode (the button right above the ball reduces the speed to your set level when you need very tiny mouse movement for delicate aim or control) The body is SOLID! made of metal and comfortable grip rubber similar to high end controllers and has a magnetic tilt base that lets you adjust the wrist angle. (even the scroll wheel can be pushed left and right to be programmed to scroll sideways or in games to switch through menus then scroll up and down through those menus, It is just a well developed product. I put a 4 star on the price only because it was over $100 and the next lower price point is like $35, this should be in the $80 range and the $100-$120 range should be illuminated and link to most razer/illumination programs to sync your color scheme. Oh and it has internal rechargable battery that works all day on a 1 minute charge or 6 MONTHS on a full overnight charge and you can charge while using it because it doesn.t move! It's Great!

I just got the Logitech MX Ergo S Plus, and it's already making a big difference. The trackball design means I don't have to move my whole arm around, which really helps reduce wrist and forearm strain, great for avoiding carpal tunnel issues. It feels solid, the tilt adjustment makes it easy to find a comfortable angle, and the battery life is excellent. My only note is that it's a bit heavier than a regular mouse, but the comfort and precision make it worth it.

I’ve always been a fan of trackball mice for light to medium tasks. This one from Logitech is a welcomed addition to the trackball history and my go to for browsing, office work and light to medium gaming(RTS, slower paced games, etc.). The inclusion of a 20°+ tilt, really makes it stand out, and out preform other traditional, yet also ergonomic mice. After 4-10 hours of intermittent use, your hand/arm does not feel as if you’ve been on the computer all day, I’ve yet to experience any fatigue. The inclusion of the precision button, thumb operated near the trackball, is a great feature along with the five other programable buttons. Editing their function for different programs has made everything quicker/easier. Not having to replace batteries is another welcome bonus and after months of use, have t had to charge. I think Logitech really made a standout product with this one, and are the obvious forerunners in this market. Please continue to make and innovate these types of mice.

I've always had a trackball mouse from Logitech before this upgrade. This one has an optional elevation attachment for an extra 30° angle for better forearm posture. It comes with a dongle and bluetooth connections. The trackball has precise rolls to where you want it to locate and you can adjust . Quick charging that lasts long. The only thing I would suggest it they could have a brighter color for the trackball as the 'iron ore' color is boring to the eyes.

I was apprehensive when I made this purchase due to its unique design and whether I was gonna get used to it. Fortunately, I did. Using this mouse requires your thumb a lot which i wasn't used to but i wont go back now. The hand position is super comfortable with 0 fatigue for long hours. Plus logi options app provides tons of customization options that you can use to define what each of the mouse buttons do for each of your favorite apps. The clicks are super tactile and have a nice feel to it. This has an in-built battery that can be recharged with a USB type C cable, super convenient. When I bought it, the mouse was at 40% and lasted me a full month before I charged it so battery life is amazing.

For heavy excel work I’ve always preffered trackballs as you need very little desk space and minial hand movement to traverse a large display. I had the basic basic version for years and loved it, but the additional features such as side scrolling wheel, extra precision, and dual link puts this new model in another legue. The multiple ergonomic positions help a lot with fatigue too.

My old trackball was having issues, I brought it back to Bestbuy and exchanged. MS updated the trackball since my last purchase. It now has a USB C port this lines it up with most of my other electronics that use "C". After I gave it some charge and turned it on, it automatically synced to my laptop. Seems to hold a good charge. The trackball has a smooth rolling motion, my last trackball the ball kept sticking. Loving it so far, but if it has issues I will go back to Bestbuy and exchange it

What a great invention! I bought this kind of mouse because I'm an older gentleman and I've just bought a new computer, so I found this mouse. It's very quiet and easy to use. There are many buttons, but I haven't figured them all out yet, but I will. You're not moving your hand all around all the time; it seems more relaxed using this type of trackball mouse. I would definitely give it a try.

I have tried different type ergonomic mouses similar to this mouse functionalities, I think at least 35% better than other similar mouses in comparison, but of course about the same percentage higher price, for me it worth it every penny. 4 different angels, dual device option, slow cursor move button, very quiet clicks, modifiable buttons. If the price tag doesn't bother you, you are going to love it.

As long as I can remember, for 30+ years I used Logitech trackballs. Before this, I used multiple MX Ergo S which come out a long time ago, so I was waiting for a refresh. Mainly wanted to have a USB-C charging port instead of the micro USB and they finally did it. The button clicks are smoother/quieter which I like and there is a new dongle (I think it supposed to be faster, but this is not a competitive gaming accessory). Overall, it's a nice update, I hope the rubber coating will last a little longer on it.

I love this mouse! Prior to this mouse, I had to have 2, one for each computer I was using. This mouse gives you the ability to easily switch back-and-forth between multiple computers. It’s comfortable, easy to navigate and works great all the time! I highly recommend this product!

For a thumb trackball user, this is the best one available. Smooth, reliable, and ergonomic. The only downside is that the rubberized finish on the palm rest deteriorates over time. I have bought 3 of these, and the only reason for the repurchases was the finish coming off.
