Logitech - MX ERGO S PLUS Wireless Ergonomic Trackball Mouse with 6 Programmable Buttons - Wireless - Graphite

I like the new features on this mouse. Very robust and hardly moves, and I like the feature of an additional wrist plate, which is at the right angle for my hand to make mouse movements. Most of all, I don't have to make many wrist movements to move the mouse back and forth, which made my hand more uncomfortable after long use of the mouse.

Best ball mouse ever! Built like a tank, reliable, dual device, excellent ergonomic design and nothing not to like. Great for travel and just wish mine came with travel case for price. Needs a location for dongle bult in... Not sure why there is none.

I just upgraded to this from the old original one. Cannot say enough about how efficient, smooth, and just downright sexy this thing is! -K. Dale Haynie (session musician/producer - Nashville)

My brother suggested this mouse so I could get better results using a stationary mouse! It took me a little getting used to it (I'm old) but once I got the hang of it, I love it!

A nice update, continuing the tradition of the Logitech trackballs. For those that prefer a trackball or really don’t have room for a mouse, this is your best choice!

Works great. I have the onset of Parkinsons. When I shake too much, I am more accurate with this.

The right and left click buttons are far too soft. They lack any tactile feedback and the press is short and bottoms out quickly. The rest of the buttons have a snappy feel which is why I do not understand why they went this direction.

I go back and forth between this and my Logitech mouse and it's helped manage arm fatigue. The device is easy to set up and has a quality build.

Highly recommend for people who struggle w carpel tunnel syndrome.

I had a older Bluetooth Logitech battery powered. Wanted to upgrade to a rechargeable model. Great ball movement, smooth action.

On / off switch aquarium to use, without picking up the mouse. I added a short straight shaft, and optical dots to verify switch position.

Mouse works great on Mac and Linux. I do wish there were additional angle adjustments. The biggest drawback is a weird scratching sound when flicking the ball mouse. This also affects the feel of the mouse. Canned air did not do the trick so I am assuming there’s something physical that’s causing the issue.

The ability and precision to move the cursor (pointer) and click or highlight where desired without shuttling your mouse or fingers is a pleasure and a relief from wrist strain. It is also convenient in limited space, such as on an airline seat tray. There are also flexible features for switching to left index finger for clicking and scrolling and for increasing or slowing the speed for precision. I have been using for years with reliable Bluetooth connection on PC, but ordered newsest model for its USB-C connector and charging. Don't leave home without it!

My favorite mouse. It just works for me and I appreciate the quality of the product and the design. As always logitech is the best and it is always the first place I go for my computer needs.

I got my first MX Ergo in 2020, and recently bought a second one (first one still works) to keep at the office while my original stays at my home office so I no longer bring the one back and forth each day. I also wanted to upgrade to USB-C. I’m happy to say that the MX Ergo S works just as flawlessly as the OG. It’s the most comfortably daily driver I’ve ever used, and I was once the biggest antagonist of roller-ball mice. I have comically large hands (just over 4inch wide palms, 8.5inches tip of middle finger to bottom of palm before wrist) so fitting a mouse is hard work. This one isn’t too big, for normal hands, and for me it’s actually comfortable in that it doesn’t force me to curve my hand around unnaturally; the included wedge is perfect for compensating for the extra width of my palm. The roller-ball is also incredibly smooth; you may need to pop it out and clean it once a month or so depending on your personal environment but this is quick. I just pop it out and grab a cotton swab, about 2 minutes total time. The battery also lasts so long I actually haven’t paid attention to it so I can’t give a good estimate. I use it everyday for 6-10 hours, and I charge it maybe 2-3x a quarter at most? The last thing I’ll mention is that despite its size, this is the perfect travel mouse! Sure it’s slightly large, but the benefit is you can just rest it on your tray table or lap while using it since the roller-ball does all of the work!

Good mouse, a bit bulky and the bottom part becomes disadhered a little too easily. I have big hands and find this bulky, it must seem huge to people with normal hands. Also I wish I could use the mouse without the bottom adapter.

Great Product. Quality construction, reliable, and accurate.

this version require double click to switch between devices. not a fast thing like previous version

Love almost everything about it - just realy big (tall) for my hand but it the one that had all the features I needed. Otherwise - great mouse!

I've been using Logitech for years. I recently tried to go to Kensington, but issues with their trackball made it so I came back to my tried and true. I just wish they would make it work with 3 devices.
