Customer Ratings & Reviews

Love the mouse. It was weird at the beginning but I’m getting used to it. I travel a lot for work and I need this mouse to work on architectural software. Usually I use the portable tables and with other infrared mouses it was always required to have a mousepad that I usually don’t want to carry.

Trackball is waaaayyyyy easier on the wrist than standard mouse. Also takes less desk space. Adjust the mouse acceleration for the position control you want. Works well for gaming, too, when you can't waste a glance to find the mouse, because a trackball doesn't move around.

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.

The best ergonomically efficient mouse. No issues with the Bluetooth.

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.

Great ergonomic investment. This has made work so much easier and more comfortable.

This is a great trackball mouse. Comfortable to use and perfect for my small desk.

Very comfortable and ergonomic! Ball tracker is smooth and fluid, the center scroll wheel is great as well. Very much and upgrade from my old "move it around" mouse, i should have bought this style years ago. Easy to use, plugged in the USB to the laptop, installed battery in mouse, synced it with the button on the bottm and you are all done.

This mouse takes a hot minute to get used to. But its AMAZING. I will never go back to the old style. I feel like my productivity shoots up atleast 10% or more. But who knows maybe thats not true. But what is true is you need this mouse. Lol

Wish I had purchased years ago. Connected immediately, easy to operate and saves strain on wrist.

Most excellent, option for Bluetooth or remote wireless USB connection. Ease of use, extremely reactive

I've been using trackballs for over 20 years and the latest version of logitech's wireless one incorporates everything you need and nothing you don't. The overall design is smaller than the last few but not so tiny as to be easily lost. The ergonomic touches in the surface are a nice touch.

I love it!!!! So easy to use. Very accurate and love that I don’t have to move my hand around to use it.

I purchased the M575 to replace an M570 that was unhappy with my new Windows 11 computer. The M575 worked flawlessly, and I programed the extra buttons as copy and paste which I use very frequently. Would highly recommend this mouse and suggest a Logitech wireless keyboard which can use the same unifying receiver (USB insert).

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.

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 know some people hate these type of ergonomic mice. But after only a couple minutes of use, you really start to love it. I never want to go back. The ball rolls smoothly and efficiently. The added programable buttons near the left click are handy. The use of the Unifying adapter makes connectivity simple.

A Best Buy employee suggested this same item many years ago when I went in to buy a mouse. After many years much use it gave out so I went in and bought another one (same model). It works great! Better than a regular mouse.

Love my Logitech track balls!! Been using these for years and needed another one to use with a laptop. This is the newest model and didn't really see any changes, works well like all the other ones I have. Easy to set up, plug in the transmitter, open the software and turn on the trackball, done. Really don't have any negatives to say about it, very happy!

I have always used a Logitech from as far back as I can remember, and I don't ever use a mouse. This particular design of trackball is one I have stuck with for over 20 years. I get about 4 to 5 years of life out of them and am more than pleased with the simplicity of installing and using it, and they are not expensive considering the use that I get out of them.
