Customer Ratings & Reviews

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.

The roller ball mice are supposed to be the best type of mouse for ergonomics, and this one is well made and another quality device from Logitech. Unifying received means you can add other Logitech Unifying devices to it without eating up precious USB ports.

Very easy to use. Comfortable and very user friendly.

This style of mouse is my favorite! I used to play PC games and this is what was used for the easiest movements in the game. However, I use it now because of stress that was being put on my wrist from work and constantly using my wrist so much that it was becoming painful. I remembered this style of mouse from my gaming days and purchased one to help keep my wrist still. I purchased a mouse pad with wrist support in addition to this and I haven't had anymore pain in my wrist. Another plus, nobody at work can get the hang of using it, so nobody messes with my computer.

The Logitech - ERGO M575 Wireless Trackball Mouse with Ergonomic Design - Black is a very good option for people suffering from wrist/arm pain due to extensive mouse use, the new Ergo MX trackball is more comfortable but more expensive

Excellent mouse for the price. The ergonomic ball was odd to get use to for the first couple days, but after that it has definitely helped overall with my ergonomics. Great for working 8 hour days.

works great. nice to be able to do all the functions of a mouse without having to move it around. fits nicely in your hand. well built and good quality

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

I've been using these Logitech track balls for decade and they are fantastic! Easy to use, save space and very ergonomic. Highly recommended!

I absolutely love using this mouse! It takes some getting used to, but the trackball moves nice and smooth. It makes navigating across multiple screens super easy. Essentially, it reduces the amount of wrist movement needed, and it's helped reduce soreness in the wrist by a lot. I liked it so much, I ended up buying 2 more.

I work from home & my profession requires me to be on the computer for 10+ hours a day. Over the last few years, I've developed an extreme sensitivity in my right hand - the mouse that I had previously is your generic mouse, but my hand would start to tingle as my shifts would progress. After I purchased this mouse, it was a game changer! Keep in mind - it does take some getting used to, but once you get the hang of it, it is the one of the best purchases I had ever made.

Easy to set up with Bluetooth, and immediately made a positive impact on wrist pain. Overall happy with this mouse. I had another one but it broke within the first year. I hope this one lasts longer.

I found it easy to use. The design made it comfortable for my hands and arm as I use the mouse a lot in my line of work.

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 is a great device. Logitech makes top notch products. I have an older version that I use often in a space where a mouse will not work. This one has bluetooth capabililty, which is an added bonus. I bought this one to pair with my laptop when I am on the road. Makes life easier.

The mouse great, easy to use and fit better in my hand comparing to an older model that I had (not moving correctly any more).

Great Mouse selection, small and ergonomic!!!!!!!!

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.

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.

The fine repetitive movement using the traditional mouse started to take a toll on my wrist. Ever since I changed over to this mouse the pain has totally gone away... night and day. Some reviewer commented on the trackball getting dirty (from eating while working). An easy pop out of the trackball (push the ball from below the mouse), wiping it with a soft cloth or paper towel) and snapping the ball back into the mouse make it good as new. I am going to consider getting the ergo keyboard once I do some more research
