Customer Ratings & Reviews

I love that i can toggle between two different computers with the push of a button. It is also very easy and comfortable to use.

Easy to use and highly customizable. You can even adjust how it sits on desk for optimum comfort

Love this, had another one that used batteries. Always had to change batteries out and sometimes didn't have available when I needed. This one recharges and one charge last months.

With this mouse, I was able to go between my Mac and surface pro. Took one star off because the instruction wasn’t clear on how to set up initially. Apparently I have to pair both devices at the same time.

The BEST mouse I’ve ever used in my life. So comfortable, very quick as well!

One of the best devices to get to stop carpal tunnel or prevent it.

I love the M570, and this is an impressive upgrade. The precision control option can be handy, the tilt can be more comfortable, and the "charge once for 4 months" saves carrying spare batteries.

This is the best, most accurate, most comfortable trackball I have ever owned. The precision button slows down the movement of the cursor when small movements are need. Well worth it.

I’ve bought this line of mouse for years. I started purchasing this Logitech mouse since the ball was red. I highly recommend this mouse.

Nice ergonomic design and color way. I was also able to sync to both of my laptop and desktop, and switch back and forth with ease.

I used to love trackballs, back in the days of Windows 95 and 98. Logitech had some great ones back then. I had high hopes for this one. Ergonomically it works well. Very comfortable, and I liked the tilt options, both without the base and with the base - plenty of angles available for just about anyone's comfort level. Buttons were precise, no missed clicks. The ball control was good, and the high DPI switch worked flawlessly. But the scroll wheel - no way to unlock it, always ratcheted, so scrolling on a page is an arduous process. You can't just spin it and have momentum go. That was what ruined it for me, having to spin it every little bit for every cm of scrolling... I ended up returning it due to that, but other than that, quality build.

First time using a trackball and was a little nervous. Got comfortable using in after a few days and it has been a huge help on my wrist and arm when working for long periods on time. Love it!

Absolutely love this track ball. A little more than I wanted to spend, but I am loving it now. I would recommend it if you're looking for a track ball.

I have both Logitech this one and the M570. What a world of difference. The MX-ERGO is very solid and easy to use. Battery seems to last a very long time and has many features.

Very nice, the comfort is 100% on point. I don't like how the scroll is not as sturdy and smooth the older version I have. The tilt is great

This mouse has amazing ergonomic features. Having sync with Bluetooth is nice no need to take up a USB port. Also the addition of the Percision button helps with lining up shots in FPS.

tl;dr - consider buying if, 1) you're familiar w/using a trackball, 2) you want a trackball that controls two computers, 3) you want an 20º angle (or 30º with the base that comes Best Buy version), and/or 4) precision mode is desired. If not, the M570 is a better value. I've used trackballs since corded Trackman Wheel (early 2000s), then upgraded to wireless M570 five years ago. Decided to try the Ergo because I had some Best Buy points and $10 off Best Buy birthday credit. I like that the Ergo can control two computers. I'm neutral on the different angles, and haven't really used the precision control

I have used many trackballs over the last 28 years. This one is the most comfortable ever. I love the adjustable angle and the scroll wheel is well placed. Surface is non slip and fits the palm very well.

Perfect for office use but not gaming obviously. Helped with not hurting wrist

This trackball is like the cadillac of the old MX570 that i have owned for the past 2yrs and this new MX Ergo has so many upgrades with a rubber coating on the top with a precision ball and scroll wheel !! The adjustable magnetic base with a extra pad to make a more angle adjustment is so nice for comfort with no strain on the wrist all i can say is someone was paying attention to this cause the discomfort i had before is almost gone when i use this trackball. The connections are very useful so if you want to use the unifying dongle or if you want to link up the bluetooth its up to you but FYI the bluetooth is alot easier unless you already have the unifying dongle on a keyboard and setup for more devices ..
