Customer Ratings & Reviews

I have had to use these types of mice at work for about 15 years, because of carpel tunnel. Most people I know don’t like or can’t use these because they are not used to them. But for me they are a life saver. I have 2 of these, 1 for home and 1 for in office work. They work flawlessly, never had a problem.

Great mouse, scrolls very smooth. battery lasts months.

I had the same wired Logitech trackball for longer than I can remember, and when I had to finally get a new one, this was the perfect option! Classic style that fits perfectly under my hand. Excellent scrolling, clicking and ball movement.

Works great right out of the box. Intuitive and comfortable.

I have been using Logitech Trackball mice for years. I started using them when I was programming. Made it a breeze. I continue to use them to this day just for the convenience and comfort of use. They wear out after 6 or 7 years of continuous use, so I am glad they are still being made and getting better all the time.

Love it, blue tooth plus it has the unifying receiver as well

Great product for people with big hands. This is my second one to purchase so I can have one for each computer.

Love it! Have one at work, now have one at home office.

It’s been working well and cannot go back to regular mouse.

This is a little harder to get use to using. I played games to help become familiar with the mouse. It is okay, but I have switched to my regular mouse. Because of the design and features I will go back to using th ERG"O.

I bought this to replace my decades old M570 trackball. It's so nice to have the wheel move effortlessly again! Bought it with a Logitech recycle couple to save $10

I love Trackball mouse's. I prefer to just run in to Best Buy to purchase. It is something that is used daily that just fits.

My everyday mouse. Very easy to set up and very accurate.

Works great! Very smooth, easy to set up, and easy to use

My order was messed up for some reason and a rep walked up to me and got everything fixed right away. thank you. It is so refreshing to not have any trouble

Perfect for when I dont have a table handy to use a standard mouse. Im movijg around all the time, and can just set this on my leg and it works perfectly.

Logitech makes great stuff, this was for a client, I recomended it to replace an outdated model he had previously and he loves it!

A very solid trackball for 3d rendering/slicing models. Has a good shape and feel in the hands. Battery life is ok and unfortunately uses a single AA battery. 4 stars.

Works very well. Easy to use. Conserves desk space

I am doing this review for my wife, who actually uses this ergonomic mouse. Long story short, she LOVES this Logitech wireless trackball ergonomic mouse. This is her second one since she wore the first one out over many years. My wife is on her laptop almost as long as I am, only her fingers and hand start to go numb after several hours on the computer when using a 'normal' mouse. By using this type of design, her fingers and hand (right) last a whole lot longer during the day. If anyone else suffers from this type of condition, this is the mouse for you.
