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

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 connectivity, battery life and well made. Great design, responsiveness, and comfortable for big hands. The price is a little high but I bought 2 of them. Great product. I initially hesitated due to the price, and bought another brand that was half the price. Won’t be making that mistake again

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.

I had the previous one with the blue ball and loved it.This one is even better!Things I love:-tilts to any angle you like-clicks are super quite and smooth-ball moves with precision and good weight-whole unit is sold and professionally built-So so items:-no charging cable but common usbc-bluetooth is usba so need an adapterOverall though super helpful for precision computer work

Let me start with, I love the previous model of this mouse. I have purchased 3. 1 for my office, 1 for at home since I work in office some days a WFH others and don't want to forget to grab it at 5am when I am half awake... the 3rd was a replacement because I wore my first one out.One of the things I loved about GEN 1 was that it used the Logitech Unifying USB FOB... so I didn't have to swap FOBs wherever I was located. It meant 1 FOB for both mice... plus other Logitech stuff I had (for example I kept a small standard mouse and keyboard in my travel bag). I was disappointed to see this uses a different FOB tech that is not compatible...So this meant I would have to use my 2nd USB A port for this... which I didn't want to do. So I had to connect this with Bluetooth instead. Which is fine, but I generally prefer to use the 2.4 ghz wireless FOB instead of BT because it is more responsive to me and connectivity seems to be more consistent.So I knocked 1 Star off for that.Otherwise this is basically the same as GEN 1, except the click is much quieter and it has USB-C for charging. Shape and feel is exactly the same. My big reason for switching was USB-C because this was my last device that used Micro-USB and I wanted to stop carrying extra cables or finding my Micro cable at home to charge up. 1 cable for "all the things" (Mouse, Work Laptop, Mac, gaming mouse, iPhone, iPads, Airpods, battery packs, portable hard drives, Gaming controllers, etc...) is quite amazing.Also for those who might wonder, the BASE is the same as GEN 1. So the "lifter" that comes optional... and at times is more expensive model... you can use the GEN 1 base lifter on GEN 2 models and it fits the same.Overall, I do highly recommend this mouse. It is the best trackball I have found after using trackballs for probably 15 years now.
