Customer Ratings & Reviews

I really like the tilt feature of this mouse, but the left click button keeps on getting stuck. For a mouse that costs $100 this should not happen. Especially when its $20 predecessor does not have this issue.

The MX ERGO works great right out of the box and the trackball is smooth. There are some improvements that would be greatly appreciated, mainly USB-C and improved rubber shell. There are reports that the rubbing shell will degrade from heavy use.

I found it super easy to use and like the fact that you don't need to move the whole mouse just the ball. You can use it with the smallest amount of space.

Bought a cheaper track ball that wasn’t as good as this one. This one literally saved me from going on workers comp! You won’t be sorry.

Bought one for every employee of my office for CAD productions.

Very nice and comfortable to use. It has helped me with shoulder and wrist pain I get from using a traditional mouse.

One of the Best Track Balls Ever. Very durable and long battery life. Needs usb C charger though.

I use it predominantly during my editing within Adobe apps like Illustrator and Photoshop. After a few days the thumb navigation becomes second-nature to you. The tilt feature using a metal/magnetic base is great and when combined with thumb-based tracking, it greatly reduces the strain of using a normal mouse. Highly recommend it! The only downside is they didn't include a place to store the little usb receiver like they did in older models. So that thing is bound to get lost at some point...

I bought this for tendonitis I’m my pinkie finger..it fit perfectly in my hand and the use is easy! I no longer have tendonitis

Bought to help with pain in elbow to minimize arm movement with a traditional computer mouse. This mouse took some getting used to, but now that I've had it for a few weeks I'm glad I spent the money on it.

Very happy with this purchase. Had a trackball mouse before but the ergonomics of this is definitely worth the switch.

Started having some sever Cubital Tunnel pain and finally linked it to my iMac magic mouse. Tried Microsoft ergonomic mouse but no improvement so I bought this and it's been night and day. No more pain after sitting at my desk all day and it's actually very easy to get used to. One thing I will say is that I've had to take it apart a couple of time already to clean out the socket due sensor being blocked by dust but other than that it's great.

if you like this type of mouse this one is a winner you can tilt it on its side for ergonomics and it feels good in the hand

This mouse saved my index finger. This ergonomic design works for me

Exceeds my expectations. It's very comfortable to use. Has additional tilt, which fits my hands working angle better.

Best mouse ever! Feels great and sturdy in my hand and switches between my laptop and ipad like a dream.

Pros: - ergonomic (I love size and shape) - impressive battery life Cons: - mouse is not designed to store dongle (ridiculous) - infrequent periods (once/twice a day) of unresponsiveness for several seconds (on Ubuntu and Windows) - the extra spacer is only compatible with one of the angles (of which, there are 2 options, which advertising seems to be misleading about) - more customizable thumb buttons would be nice

Great product for what I’m needing it for. Almost a month and recharge not needed yet.

This is the perfect accessory for my MacBook Pro. I really like using the ball to move the pointer.

Much more functional than the M570, mac compatible, able to switch between mac and pc, two pc, two macs, wit the click of the button, side scrolling, and the tilt feature is nice, wish the tilt feature was more thought out it as for a product of this caliber it seems to be after thought, however it does make a difference in longevity of use. Overall if your currently using an M570 you will not be disappointed if you buy this mouse.
