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

I love this mouse. I can’t function with a normal mouse anymore. Connects and user friendly to all my devices. It’s pricey, but well worth every penny. Charges easily, battery lasts longer than I would have guessed it would. Be very careful cleaning it, don’t get any kind of moisture near the lasers. I ruined my first one that way, but otherwise, it’s the only thing I’ll use.

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.

Note, given I've used 3 of them, this is the best. I wanted a thumb controlled trackball since I have severe wrist problems. I tried vertical mice and they helped but not perfect. Then I tried a cheap vertical trackmouse and was surprised how usable it was and how quickly I adapted. Plus my wrist pain was gone! BUT that one didn't have the smoothest ball. So I found a mouse that was 2x as much and .... it was pretty much the same and wasn't vertical. So I decided to splurge and go all out for this one. I DONT REGRET IT! It's worth all the money. Smooth ball and then that precise mode button is great. I'd just like more buttons like the index finger trackballs (not good for me because you have to move your wrist) but thad just be a nice to have. The only actual complaint I have with this mouse is that it isn't vertical enough. It has a pad that can increase the incline to 20 degrees but that's not enough. Luckily I've got a 3D printer and was able to print an additional 40 degree incline so I have 70 deg now which feels perfect! TLDR: Great and worth the price (though it is pricey), but would like more buttons and more incline options to make it vertical.

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.

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.

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.

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.
