Customer Ratings & Reviews

This is the best mouse if you suffer from Carpal Tunnel or have had surgery for C.T. This doesn't need to be pushed around the desk since you use your thumb to maneuver the trackball. and since you arent pushing you don't need to "grasp" or apply any pressure. The clicking motion is relatively easy as well.

I LOVE this trackball. I had the other Logitech where they had switch issues for the two big buttons, but this baby has been great for two years now. I bought it the day Best Buy put it on their shelves. Keeps a charge for a month with heavy usage, pop up on screen tells me when its time to charge, 5 minutes will give you a complete day if needed. Yep, its a little bigger but I like its solidness and the bottom with the anti slip coating is great on my real leather recliner. Again, I love this product.

I was skeptical at first when I bought this and it took a little getting used to, but now I’m hooked. I never realized how much easier using a computer is with a trackball. In my opinion, this is the best mouse you can buy. I highly recommend it! After using it for so long it’s hard to go back to a regular mouse. I also love the way you can customize it with shortcuts. I have certain buttons bring up a calculator or change pages without needing to do anything on the computer itself. It’s a little pricey but worth every penny!

It took a little getting used to but now I prefer using the trackball over a conventional wired mouse. It comes in handy since I don’t have a lot of space on my desk and using a double monitor setup at work means I’m constantly making several swipes to move the mouse with my hand. Of course I still need to do a few swipes on the trackball but I don’t need to move my hand. If my wrist gets uncomfortable I angle the mouse and hold it differently but I can still use the trackball.

I've used the traditional roller ball mouse for years, and loved it, until I upgraded to this one. Now I know what love is! This mouse is so smooth. The included wedge and angled plate allow my wrist and hand to sit at a very comfortable angle. I spend 9-12 hours a day working on my computer and the difference felt with this mouse is greatly appreciated! I no longer have pain in my wrist halfway through the day, I'm able to work painlessly all day long. I can't recommend this mouse enough!

Comfortable for the wrist, easy switching between monitors. Long battery life. Really like the flexible positions it gives the wrist.

This is a great track ball mouse. I like the ergonomics and ease of use on this device.

Logitech releases a bluetooth tracker ball, pin point positioning accuracy, and sips battery life extremely slowly. Very pleased with it indeed.

This is an upgrade to an already great product. I bought this because of the tilting capabilities which makes it more ergonomic and custom to your hand. Huge fan of the trackball feature! Never again will I lift a mouse to move or place my cursor. Good product! Go get one!!!

This a the best mouse I have ever used. It works good and is comfortable to use. I have less wrist strain due to the ergonomics of this mouse. it has several programable buttons and is well built.

I have owned many Logitech devices. Although a bit large, this trackball meets my expectations. The option to tilt it is a nice plus.

After having both an M570 and M575, I finally decided to spring for this trackball. As great as both of those are, the angle of the Ergo suits me better, and even more so the extra 10 degrees with the Plus. Micro USB is lame, but not a big deal. The things it really needs for the next refresh is two or three more custom buttons and an inertia scroll wheel, especially at this price.

I loveeeee this mouse! The ability to switch between Bluetooth and the unify wireless receiver is seamless, and great. My only complaint about this mouse is the placement for precision mode. I can see how it can be extremely useful, but personally I find myself actively trying to find my cursor only to find that it was switched over and hadn't moved from the original position all that much. The battery life is FANTASTIC. Honestly. It's a great buy.

Easy to pair, easy to use, doesn't hurt my hand or thumb

Easy setup, adjustable sensitivities for scrolling. Love the adjustable angle of the stationary position.

This is my 1st TB mouse and this thing is awesome. I like the fact that I can customize it with the programmable buttons....production is off the charts with every project I've worked on. The 20% tilt is the most comfortable for me but it's nice to have options if my grip or wrist get uncomfortable. After 1 week of use, I increased the pointer speed as I've gotten more use to it over a traditional mouse...SWEET PURCHASE !!!!

I was not going to spend $100 for a track ball mouse with so many options out there and nearly 2 decades of using a wireless traditional mouse. I looked at the net Logitech model down that didn't have the extra ergo's. After some hands on feel of the controls I took a chance with the MX ERGO. I found after several days reduction in should strain and glad I went with this model.

I love this trackball mouse. I have owned the M570, but the one thing I didn't like about it was that it wasn't bluetooth. Love that this one is, and since I work on a couple of different work stations, I can easily take this with me. I also like that I can adjust my hand to two different angles to suit my comfort. The trackball works great as well. If you are looking for a trackball mouse, this is definitely one worth getting.

this is the third mouse I acquire. It is so smooth and precise. It is also fast and easy to adapt.

very easy to use, the angle is easier on my hand and wrist, no pain like with the traditional mouse's Ive used in t he past
