Customer Ratings & Reviews

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

Its really easy to setup and very simple to use. Really enjoy the mouse.

Great mouse. Easy to use and like track balls much better than a normal mouse.

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.

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

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.

Just perfect, easy to use and rest your hand while work

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.

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.

Great with use without any base support & a bit heavy

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.

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.

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.

Holds a charge for a long time Fits my hand well

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.

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 roller ball mouse is great for easy use with laptops.

I've been waiting a long time for a Bluetooth trackball, and finally it is here. Works great, has multiple angles of use, and many extra features (like the "slow" cursor button). Overall, I am very happy with this purchase.
