Customer Ratings & Reviews

It is excellent for software developers having a good response and great features like been able to use in multiple devices at same time.

Have used this style and brand of mouse for years and the upgrades in this model are well worth it. I love that it's rechargeable!

I really like this mouse. It takes some getting use to with using your thumb to move the cursor, but works great when you get the hang of it. Buttons have a nice click and very responsive.

Superb: for my macair :very user friendly Love the tilt position change and zoom

This is a decent mouse if it fits your grip. It is fixed on the desktop so might not be suitable for some apps.

My daily use mouse for a good reason. Work on my computer most all the day and this mouse feels wonderful and a good number of programmable features. Love it.

Great flexibility with the trackball. It can easily adapt to my kind of usage for detailed work and navigation. Good investment.

Buttons have less travel than the m570; scroll wheel is much more tactile. Adjustable slope is great for comfort, especially the plus edition with the extra base plate. Back and forward buttons could use some work, shape wise.

Got this to replace my apple trackpad which was horrible - sadly bought the new one and still was not good. This has no issues, responds quick, and versatile.

My hands tend to shake and make it difficult to use an ordinary mouse. This mouse works great for me. The programmable buttons are very useful.

This Logitech Mouse is awesome. It’s fits my hand perfectly. I love the features. It is a bit expensive but I love it.

I love this thing when working on excel. Highly recommended for accounting

Very comfortable and helped with my wrist pain issues.

Like the flow between two laptop. It take care of the data transfer also between the two laptops.

After using the Ergo Trackball , i don't like other mice anymore, they feel weird!

i purchased this for my wife, she loves this product

Using this trackball mouse is so convenient when using your computer in different locations. You don’t have to worry about a surface to roll your mouse on.

I've been using Logitech trackballs for almost 30 years and love them. The MX Ergo has a great fit and the optional angle is great. However, Logitech failed miserably with their 'new' Logitech Options software. They removed the ability for the user to set the orientation that has been the most useful setting they had for their trackballs with the "Setpoint Settings" software. It provided the user the ability to set the vertical direction for whatever was comfortable for their thumb movement. But they removed the option and will not even respond to questions about restoring the functionality. Why they removed this long-time option and now expect you to adjust your thumb movement to their fixed orientation makes no sense at all.

Great. Works perfectly. Very responsive and easy to customize

Great shape and quality, however trackball can easily get clogged and not roll as easily until cleaned out. Also the MX keys is USB-C I wish this was as well… more cords.
