Customer Ratings & Reviews

This roller ball mouse is great for easy use with laptops.

The best trackball mouse to ever exist. I’ve gone through the two previous versions by Logitech and this one’s build quality is next level. The new angling makes all the difference for comfortability.

If you are looking for a trackball mouse this is the one to beat. I love the different wedges/angles that the mouse is able to be tipped to. It makes the ergos amazing no matter what your setup looks like

i hated most trackballs before. but in my quest to find a mouse that would not aggravate my carpel tunnel, this was the clear winner. the adjust angle is great. if anything, i would want an even steeper angle

The trackball has been wonderful for helping relieve stress on my arm and upper back. I use the mouse 6-8 hours a day and I can no longer feel the strain at the end of the day from moving the pointer around the screen.

For years, I used a standard mouse, then switched to a vertical mouse once I developed wrist pain. Even that did not fix the issue entirely, so I switched to this after watching a video online. I can say without a doubt that this is the best, most comfortable computer input device I have ever used. Getting used to using a trackball does take a bit of work, but not as long as you'd think. Within a day or two of adopting one instead of my work mouse, I was functioning normally. It is particularly fantastic for tasks that require fine movements, like photo resizing and editing, as the "precision" button that slows down the cursor works really well.

Easy to connect and use. It is a bit large to drag around.

If you are a fan of trackball mouses like I am then I highly recommend this mouse. The fact that it is bluetooth, rechargeable, and has a precision mode means that Logitech put some serious thought into this product. I spend most of my day creating and editing music and videos for school and I love this thing.

Takes a little bit to get use to using the Trackball but is great once you get used to it. Very comfortable.

This product is simply amazing. I am able to be more scroll a lot faster as I work between the triple screens in my office. This is the second one I purchased for my home office. It definitely is a great buy.

I thought I’d hate this, but what I ended up hating with the Ergo trackball. This fits my hand perfectly and is very accurate. As soon as I figured out how to adjust the scroll I was off to the races, in first place.

This product is a must-have for those with old fingers that can't seem to grasp the small button any longer. Honestly, I've used the stationary mouse for years. I like not having to move the mouse around.

Great Mouse!! Very easy to use and comfortable. Love it!

Solid device that felt a little odd in the beginning, compared to my old trackball. After a few minutes, it was like I had been using it all the time. Good heft, multiple options, and easy to understand and use controls.

Love this mouse, very ergonomic, thinking of naming it...

Best trackball out there right now. If you enjoy trackball mice then you won't find one better. If you have never used one before, I recommend saving your money and starting with the base model for allot less money.

This is the next generation over the one I used years back and it works beautifully. Several significant improvements including very useful extra buttons and making it rechargeable via USB make it much better than the old version.

This is a well designed trackball, that’s very ergonomic with great button placement, and several angles for tilting the entire device. I use this for gaming and really enjoy the quick response to both the trackball and the button presses.

Holds a charge for a long time Fits my hand well

Really good mouse. Smooth tracking and a pretty long battery life.
