Customer Ratings & Reviews

I like the way the mouse is designed. I have smaller hands and it fits well. The battery is still going strong. Would definitely get again.

I have limited desk space. Bought this during Black Friday deals. I have a much older wired version from 20 years ago. I decided to get this when I was browsing. Took some time for my thumb to get reacquainted and to relearn the control. It is much lighter in weight. I like that I can use a regular battery. My use is strictly for general purposes and not gaming. From what I understand, gaming mouse have a much higher dpi for accuracy. This device works best for me for scrolling long documents or web pages.

Excellent ergonomic mouse - stationary, easy to use - minimal wrist movement

Great mouse. We use it blue tooth and it works well and hooked up easily. The ball is sensitive and easy to use. After using this style, it is hard to use the standard style mouse, this is so much better

Simple to use. Allows me to do things quicker than a regular mouse.

I've been using a ball mouse for years. Can't figure out why anybody would use anything else. works great on a clouded desk or on the move.

I've bought this mouse multiple times and never regret it since I work on a computer everyday ranging from 4 hours to 10 hours daily. I felt a huge difference with the switch for my wrists.

Great design, easy to use, easy to maintain. Convenient. Comfortable. Lasting. All family members using one.

Reliable. Now with Bluetooth support so one doesn't have to use the Logitech unifying receiver. However,being able to pop the Logitech unifying receiver into a usb port is very nice when using someone else computer. I strongly prefer the MX Ergo, but if cost is a concern, this is a good alternative.

The Ergo Trackball Mouse is perfect. It allows me to make precise cuts in my audio edits, and keeps my fingers from getting tired.

I spent years loving my M570 trackball, but hating that the dongle took up the only USB port on my surface. The M575 is the M570 with Bluetooth. So much so, that when I decided I liked the color of the ball in the 570, I swapped the ball from my 570 and put it in the 575. As far as cost goes, why are trackballs more expensive than mice?!? Compared to other trackballs, the price is fair for what you're getting.

This product really helped take the strain off my wrist from using a traditional mouse. Not having to work the flexion and adduction youbnotmally would to navigate a traditional mouse is an added bonus. I should have made this switch years ago.

Love the design of this product! Very smooth operation.

It is easy to use. Easy moving motion great ease on the wrist. Less pressure on fingers and wrist. Wonderful to use.

This mouse has been a huge help with our Laser cutting machine as the main computer has limited space for keyboard and mouse. This eliminate haveing the need for movement room. Takes little time to get used to and is comfortable for the opporators. It also handles dust well.

Great mouse. Good fit for my hand. Easy to use. So much better than traditional mouse or laptop pad.

It was recommended by the ergonomic specialist at work about 5 years ago to switch over to a trackball mouse. After trying a few different ones, this particular trackball mouse (well, the previous model) was the one that made all the difference. I reluctantly agreed to change. I am an analyst that deals with huge amounts of data and really didn’t want anything to slow me down. It’s safe to say I log more miles on my mouse than anything else in life . After a few days of getting used to, I was so pleasantly surprised that I never looked back. Not only did my wrist/arm/hand pain go away but I was much quicker. Not having to drag your whole arm around to move the mouse makes a big difference in so many ways. Needless to say, this purchase was my 4th or 5th Logitech trackball in this particular design. It was the first of this newer model which, of course, I was reluctant to switch to. This newer model seems just as comfortable as the old but the ball seems slightly tighter (best way I can describe it). This might actually be ideal for some but I am a creature of habit and I liked the looseness of the original. It wasn’t to the point that I have put this away and looked for the older model but just an observation. Given the choice, I had one or two of the older model die out on me over time so if this one lasts longer I’ll deal with the different resistance of the trackball. Either way, hands down, if you are looking for an ergonomic trackball or any mouse in general I 100% choose this one over all the rest.

Works great and relieve stress on my hand. No more carpal tunnel.

Plug and play that is to install to my lab tap no programming

I love my roller ball. Logitech or Logi as they go by now. I have used this roller ball since 2004. Of course it was a relic compared to the roller ball of today. It has saved my wrist from carpel tunnel and my thumb is still working great at 67 years of age.
