Logitech MX Ergo Plus Wireless Trackball Mouse, 2048 dpi Optical Sensor, 8 Buttons, 4-Way Scroll Wheel, 910-005178 (Renewed)

Best wireless mouse ever - I have 2 and will continue to buy them. Smooth feel, weighted quality, very durable, and the battery last for a long time for every charge. Love it.

Had this mouse for about 4 years now and it is excellent. No more strain on the wrist. The battery lasts forever and I love being able to switch from dongle to a Bluetooth connected device at the touch of a button. Would highly recommend.

These are great mice to use at work. small real estate footprint on your desk, customizable for your line of work, portable if that matters to you, and definitely ergonomic. Trackballs have come a very long way and I prefer them to normal mice now. I had one of these before it met an untimely end at my job. Both of them were renewed and both worked very well with my only quibble being that I replaced the trackball it came with. The trackballs it arrived with are not as smooth as they should be and it is immediately noticeable - good news however is that replacements are about $10 and with buying a renewed one you can buy 3 and still be below the full price of this mouse. They also come in cool colors so you will always know which one is yours.

If you like a track ball this is the best I ever used. I love the two different angles the others use the lower angle but I like the higher one best without the rubber base. I have 4 of them, one for each laptop and desk top. I know they have some newer fancier one but I hope they keep making this one.

After over a year of use and owning multiple Ergo MX mice (1 for home and 1 for work), I can confidently say it's an exceptional product. Comfortable, reliable, and designed for productivity, it’s become an essential part of my setup. Highly recommend!

I like these mice in general as my setup has no room for a traditional mouse, I've been going with Logitech for years as I like the Unifying receiver and using 1 port for both keyboard and mouse, Only issue I've had so far as the battery is not user replaceable and getting the ball out to clean the bearings (which you'll be doing every month or 2) is a nightmare unless you have a thin, sturdy and gentle tool to get it out.

Trackballs, in general, are something of an acquired taste. Rather than waving a mouse over more space than my crowded desk has, I long ago opted for using a trackball. It basically stays in one place, and gets the job of moving the cursor around done. The size of the MX Ergo Plus fits my hand, and the ball is easy to reach with my thumb without any "gotta get it just right". The buttons also "fall readily to hand" to use an old British-ism. As far as keeping the battery charged goes, I've yet to see the battery go flat, period. I charge it every so often, and all is well. Unfortunately, the USB socket is a micro-USB socket, and not a Type C socket. Logitech dropped the ball on this point. Otherwise, this trackball gets the job done, and does it without getting in the way of my getting my job done.

They still use the trash 1M click buttons. This mouse consistently fails within 1-2 year of regular use. For $100+, you'd expect it would last 10 years. Save the money and buy another brand besides Logitech.
