Customer Ratings & Reviews

I am still in the process of adjusting to the mouse elevation system. I have not decided which elevation to use (20-30) but as for the mouse its' self I am learning new things to use every time I fire it up. I am glad that I finally broke down and purchased it.

I have been challenged for years with essential tremors especially in my hands making it difficult to work on the computer using a mouse. This device allows me to perform these tasks accurately and confidently. It has exceeded all my expectations.

Best purchase ever! I am on my computer all day. Allows me to get my work done quicker and pain free.

Best mouse I've ever owned. The ease of use is to notch and I love it!!!

i got this to replace the trackball mouse, I'm very delighted by the multiple connection options (wifi to the dongle or laptop's bluetooth) The scroll buttons, and navigation buttons, and other options are very useful. Extremely happy with this product!

Great mouse. Long battery life. My kid loves it. Worth the money

Love this mouse!! Worth every penny! I have a wrist injury that flares up when I over use my wrist (mouse usage). With working from home, it seems as though I’m working longer hours and little rest to my wrist. This mouse had helped me a lot!

Let me start off by saying why I needed a mouse with a trackball. I produce music and edit photos/videos, if you do any of those things you know how tiring it can be trying to edit for hours with a regular mouse. After a while you start feeling that uncomfortable pain. So I moved to trackballs a few years ago. If you have never used these it will take some time getting used to. Enough backstory, I needed a new trackball mouse because my previous one broke. Now, I wasn’t sure about spending over $100 on one but my brother had one like this and he was happy. The build quality is very good and it looks pretty sleek next to my laptop. You can customize the buttons which is cool and being able to angle the mouse a bit is actually really helpful. Mine also came with a riser that allows the mouse to be placed a little higher. That’s pretty cool. I definitely recommend it.

Let’s just say if you’re not used to these types of mouses (mice lol) it can take some getting used to.. once you get the hang of it, it’s wonderful. You can even synced it to multiple computers and it remembers your settings on each. It’s sleek, comfortable, and works like it’s supposed to!

The track ball we all know and love gets a much needed update. This ergonomic version brings comfort and additional features that were previously lacking. It is built of high quality materials. Bluetooth connectivity to multiple computers is a nice feature. Great for all day use at the office.

This is a pretty expensive track ball mouse but after using different, cheaper models that are very similar to it I think it's worth the extra cost. I find the scrolling is more precise and the ability to adjust the angle your hand rests on it akes it easier to use for a long period of time.

I was having a lot of Wrist and forearm pain so I did some research and bought this mouse. Took a little getting used to but now that I am comfortable with it I must say the pain is greatly reduced. There are lots of customization options in the Logitech software.

It took a little to get used to using but it wasn’t bad since I’ve been using the M575 for years. Only issue is I keep hitting the speed control for the trackball since my thumb sometimes scrolls that way

This is a great alternative to a mouse for use with a laptop on minimum surface availability. It does everything I need, but I wish it had more buttons (especially programmable ones). I love that it is rechargeable and will work either with existing Bluetooth or with its provided USB dongle. Also, the base is angle adjustable so there is less stress on my wrist.

Comfortable and the angle adjustment is fantastic. Have had it for over a month use it daily and the battery is still almost half full. I like the idea of a rechargeable battery. Never have to worry about finding new batteries.

This is my go to ball mouse. Have one for the office one for the home office and another for my personal computer!

Solidly built. Simple to install. Battery works for weeks between charges

Favorite mouse ever. So easy to use, so comfortable. My hand doesn't hurt after long hours of working on the computer. Very easy to learn as well.

I’m using multiple computers at work and this not only makes my work Mir comfortable but also possible to minimize the clutter around me desk. It is lacking some features that their other flagship MX mouse has, but having a Logitech K850 keyboard to go with it brings many of the missing features back.

I use this on 2 laptops and I am able to toggle between two of them with a push of a button. Really easy to use! Just plug and play.
