Logitech MX Ergo S Advanced Wireless Trackball Mouse, USB-C Rechargeable Wireless Ergonomic Mouse with Bluetooth and Encrypted Dongle, 6 Programmable Buttons, for PC/Mac - Graphite

It was perfect but sadly i had issue with the disk which didn't make it comfortable for my use and this was my main reason for purchasing

Best trackball mouse I've ever used. I especially like the ability to switch between multiple PCs conveniently. I used to get carpel tunnel really bad when using a traditional mouse. Since switching to the Logitech MX Ergo S, no more sore wrists! Cleaning the internal contact points is super easy and restores smooth operation in seconds. Button clicks have a premium feel with low noise and relatively short travel. The metal baseplate ensures it stays put and grips the desktop surface so you can enjoy hours of use without it sliding all over the place. Highly recommend and will buy again if this thing ever wears out.

Love the combo! Helps with my back a lot more!

Bought this to replace one of the older models of the same trackball I misplaced. I was initially sad to see the price increased on this model from the one I purchased a few years ago, but I can tell the quality has improved so I'm happy with the cost knowing now quality improvements were made. In my experience, this specific trackball is durable and my last one lasted me over 2 years with heavy use; it stills works, was just misplaced. Overall, I love this mouse. The tilt on it is so nice for my hand and my wrists. I work in IT but also do digital artwork and graphic design as a secondary job so I'm constantly using my wrists with typing, using a mouse, and drawing. I take extra care of my wrists as I've had symptoms of carpal-tunnel flare up over the years and this mouse has been very helpful in ensuring I'm not hurting my wrists. I noticed my hand would start cramping with my regular, non-trackball mouse and my wrists would start to get sore. I'm not sure how I feel about the material yet as it seems to have this type layer with silicone feel. This silicone layer/coating does attract dust (you can see my product photos after only 1 day's use where dust is building up on the bottom). In my experience, these coatings wear over time, revealing shiny plastic underneath but I want to give this mouse a fair chance before assuming it's going to have issues with the coating. Did not come with a USB-C cable for charging but I'm OK with that if it means keeping costs down and I have tons of spare USB-C cables anyway. My only gripe is I wish they would include a slot or hidden compartment like some of their other mouses to place the wireless USB dongle so it doesn't get lost when not connected to a computer and not being used. I'll update this review if I find anything worth noting.

Très grande efficacité, très bon produit. Travail très bien, les commandes sont a la bonne place pour effectuer les tâches .

Nick’s Take (The short story) This was my first trackball mouse, purchased to help resolve wrist and shoulder strain — and it genuinely delivered. After 10 months of daily use, I now prefer it over a traditional mouse. Comfortable, precise, thoughtfully designed, and worth the price if ergonomics matter to you. 1. Context & Use Case This is my first-ever trackball mouse. I purchased it specifically to address wrist and shoulder discomfort that developed from long hours at my desk. At the time, I was using a Microsoft Sculpt keyboard, and now a Kinesis MWave, both aimed at improving ergonomics. The MX Ergo S became the missing piece of that puzzle. I intentionally gave myself 10 months of daily use before writing this review to fully adapt and honestly evaluate whether it made a long-term difference — and I’m happy to say it absolutely did. 2. Learning Curve & Transition There is a learning curve, primarily in retraining your thumb to handle cursor movement. For the first few days, things felt awkward. After a couple of weeks, it started to feel natural. Now, I genuinely prefer the trackball experience over a standard mouse. Once muscle memory sets in, the precision and comfort become second nature. 3. Ergonomics & Comfort This is where the mouse truly shines. The angled design fits comfortably into the palm, keeps the wrist in a neutral position, and significantly reduces shoulder movement since the mouse itself remains stationary. After extended use, I noticed: Reduced wrist fatigue Less shoulder tension More relaxed overall posture For anyone dealing with repetitive strain, wrist pain, or shoulder discomfort, this can be a game changer. 4. Build Quality & Features The build quality feels premium and solid. Highlights: USB-C rechargeable (a feature I didn’t know I needed, but now greatly appreciate) Bluetooth connectivity — extremely helpful for workplaces that restrict USB dongles Smooth, responsive tracking Buttons are well placed and easy to reach I purchased this alongside an MX Anywhere S for travel, and quickly realized how much I valued the wireless charging and Bluetooth flexibility across both devices. 5. Cleaning & Maintenance Cleaning is refreshingly simple. The bottom plate pops off, allowing you to gently push the ball out (a pen cap or pencil eraser works perfectly). A quick wipe of the internal sensors and ball keeps tracking smooth and consistent. It takes under a minute and makes a noticeable difference. 6. Who This Is For Ideal for: Desk workers Programmers Designers Anyone dealing with wrist, forearm, or shoulder strain Users seeking ergonomic improvements Less ideal for: People who frequently move their mouse long distances across a desk Gamers who rely heavily on rapid, sweeping movements 7. Value & Price Perspective At around $100, this is not a casual purchase — but for ergonomics, it feels justified. If this reduces pain, strain, or fatigue during daily work, the value becomes very clear. For me, the comfort improvement alone justified the price. 8. Final Rating Five stars. Even at its premium price, this mouse has delivered meaningful comfort improvements, excellent usability, and long-term reliability. It solved the problem I bought it for — and that’s ultimately the highest bar a product can meet.
