Customer Ratings & Reviews

I bought a new computer because the description claimed it had 2 HDMI output ports. It didn't. With this mouse I am able to run two computers and move between the two, including copied files, as needed. Additionally, the adjustable angle makes it more comfortable.

This mouse is quite comfortable and allows a lot of unique functionality. You do need to go to the Logitech website for details, and I found a couple of helpful youtube videos on how to customize the buttons. I may try to get one for my business, not just for home use.

Love this mouse this is actually my second one. Takes a little getting used to.

Really good and solid trackball. I loved it so much I got one for my office as well.

Love Logitech gears and of very good quality products you expect and trust

So after 2 years I need to replace it always, so I had some trackballs in my life, I don't like a mouse.

This mouse is awesome... The trackball is smooth and responsive. The buttons are quick clear clicking, and with the programmable number of buttons... I'm kicking butt.

Whether starting out or continuing use, if you want a good mouse this one is quite efficient. I got this mouse as a replacement for one for my mother to use and she has enjoyed it greatly. Has helped her out much better than her old one and is doing her an excellent job.

multiconnection is fast and reliable. good shortcut button mapping - hoping for a type-V charging followup!

This mouse is very comfortable, works great with Auto Cad/Cad Cam! I am very pleased with this purchase and Logitech products!

This mouse is good for normal use on documents, coding, or other generic files, word, excel, one note etc. But it’s not the best to use a precision mouse for drafting, the track ball is just too loose and the cursors goes over things quickly and/or not quick enough, I have used the button that makes the track ball less sensitive and all it does is making it slower that’s it. I would have love to see a track ball that clicks and/or stops exactly where you need it to be since almost every time it acts as if it had a mind on its own. Just get a normal regular mouse with good ergonomic design it will do a better job on precision tasks that need to get done quickly.

Great functionality but no place to leave the USB dongle ON the mouse, so you will have to leave it on your computer and remember it if you switch. Not a big deal with a laptop, but now I’m one USB port down.

Very HAPPY with this trackball! Meet my expectations and saves my wrist muscles. I will take a week to get used to, but you just have to retrain the brain and arm to be used more efficiently.

I use these trackballs for work. I have gone through several of these. The quality can be somewhat hit or miss. Sometimes the ball gets stuck. This happens more for some than others though. But I keep buying them.

Switched to this model from the M570. The adjustable angle base makes a subtle but significant difference in comfort, especially for longer periods of use. The precision mode is surprisingly useful, especially for professional use such as with AutoCAD, Soldiworks, etc.

I use this at work, it really helps with long-term use. I can tell when i am traveling and do not have it.

This mouse is very responsive and feels solid. It also allows you to customize buttons. Will never use a regular mouse again!

Comfortable with many options for different positions. The ability to quickly switch between multiple computers and even copy and paste between different computers is a game-changer for anyone who works on multiple computers.

This mouse is smooth rolling and comfortable to use. It hasn’t been difficult to pair and it is much nicer than a mouse you drag around the desktop. I love it!

Able to angle the mouse made a tremendous Improvement!
