Customer Ratings & Reviews

Really comfortable. A great ergonomic design. And it doesn't take up much space.

I've used these Logitech Trackball mice for over a decade and have several of the wired versions. The wireless ERGO M575 is much more convenient to use. I've been using these for several years on both business and personal computers without any issues other than an occasional battery change.

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 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.

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.

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

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.

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

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.

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

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.

Reliable thumb-roller mouse. Easy to use in limited space. Only downside is that the contact do wear out after a while so you have to get a new mouse.

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.

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

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

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.

My favorite mouse. I have used this style mouse for several years and find it easy to work. You don’t have to move the mouse at all because of the movable trackball operated by your thumb. Great for precision projects in manipulating the cursor. Highly recommend.

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!
