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 - GraphiteCarbon Neutral Certified by SCS Global Services

Why did I wait so long to go with the perfect trackball?Features I didn't even realize I would love!:- cordless! It charges very quickly, and lasts more than a week on one charge.- it feels solid! Two positions with a rubber grip bottom makes sure it doesn't slide around your desk or bed or wherever your pc is set up.- the bottom is magnetized, so it pulls right off to quickly access the track ball for easy cleaning!- since it is cordless, so easy to use it in all kinds of environments, and unlike a regular mouse that requires space to use, you need only the space that this sits in, to use. I use this on my counter while I'm cooking to change YouTube videos or Netflix movies playing on the side screen, and it has a great cordless range to the device.- it has the potential to hook up to several devices, so it's a quick push of a button to select the device, and of you go, rolling the ball and controlling the interface.My setup is a wide screen monitor hooked up to 3 different computers, I have a cordless Dygma Raise 2 keyboard that can connect to any of these PCs, along with this mouse that can also connect to any of the 3 PCs, so I have one keyboard and one mouse controlling everything on my desk. It affords the ability to have a clean looking setup, and I can't say enough how easy it was to learn how to switch between systems, and how easy it was to adapt to using a track ball mouse over decades of using a standard mouse.It's solid, easy to use, easy to clean, easy to charge, a real quality mouse that I'll have for years!

I've been really pleased with the Logitech MX Ergo S trackball mouse. Having used the previous version with its older micro USB port, this upgrade brings some nice improvements to an already excellent mouse.The USB-C charging is a welcome change that makes charging more convenient. A quick 1-minute charge gives you 24 hours of use, and when fully charged it lasts up to 120 days Amazon – so battery life is rarely a concern.The quieter clicks are a noticeable improvement that makes the mouse more pleasant to use, especially in shared spaces. Logitech has made the main buttons 80% quieter than the previous model Digital Camera World, which I appreciate during long work sessions.For comfort, this mouse delivers. The 20-degree tilt angle reduces muscle strain by 27% compared to regular mice Cdw, and I can definitely feel less wrist fatigue after a full day of work. The shape fits nicely in my hand and provides good support.The trackball performs smoothly, allowing precise control without moving your entire arm. Switching between regular and precision modes with a dedicated button is handy for detailed work. The six programmable buttons can be customized through the Logi Options+ app to fit your workflow.Overall, the MX Ergo S is well-built, comfortable, and helps reduce wrist strain while maintaining good control. If you're concerned about wrist health or prefer trackballs, it's definitely worth considering.

I love these mice. I have got four over the last 5 years. One fell out of my vehicle somewhere, one was a refurbished one that the ball never rolled right, and one I decided to clean with a Clorox wipe. I didn’t realize I had bought a refurbished one after I got it and it never worked right so make sure you buy a brand new one. The one I cleaned trying to be sanitary must have done something to the little rollers in it, took the oil off or scarred them. I tried applying light oil to them but I could never get it to roll easy again. So the only problems I’ve ever had were operator error. I do use tris with the MX Keys matched to the same dongle and I love them both

Works extremely well except for one issue: the bottom metal plate's rubber is not grippy enough. Good thing I was replacing the mx ergo: I was able to swap the metal plates out and the mouse doesn't move around on the desk when I use it. Note: the receiver IS different than previous mx ergo s. Use the new receiver: plug it in, power on the device and hold the 1/2 button until it blinks. Simple.The new clicky buttons are soft clicks btw. Very quiet, might take a little getting used to with the feedback but they feel good.Also, the mx ergo S charges with usb-c which is NOT included. The regular mx ergo uses usb micro I believe.

TL;DR: The MX Ergo is a fantastic trackball mouse and well worth the investment, especially for productivity and multi-monitor setups. Just don’t expect Amazon to treat it with the care it deserves.I am someone who is on the computer all day, so I look for comfort, accuracy, and ease of use for a mouse and this does all of what I need. Thanks to the ergonomic design, I am able to effortless use this mouse for 10+ hours a day. Switching from my older model MX Ergo was effortless and the upgrade to USB-C charging is very much appreciated.With the USB dongle and a Bluetooth connection you are able to effortlessly switch between devices. For anyone with multiple monitors I recommend giving the trackball a try, it allows you to move across large screen real estate with minimal movement. The customizable buttons are icing on the cake allowing for added function.Amazon's shipping method for this mouse is a joke. They sent it in its OEM packaging, risking damage and theft. If you find a retailer with better packaging standards, it's absolutely worth buying.

Great mouse, maintains constant connectivity, and feels ergonomic. I subtracted one star because I’ve tried other ergonomic mouse styles and prefer more support in the palm and a higher angle of tilt. That said, I could overlook the slight design critique and happily give 5 stars if it wasn’t for the USB dongle…there is no way to attach it to the mouse for travel. I have to stick it in a little ziplock bag so I don’t lose it. That’s a mistake in the design that is unforgivable and ridiculous deal with.
