Good feeling mouse. Feel like it will help in the long run.

Very easy to use. also I like for the fact that you don't have to move the mouse but just use the features on it to move around

Installed in seconds and works great. I need to buy one more.

Great replacement. I Love The newer sleeker design.

I like this product for two reasons. First, the ability to connect blue tooth so you don’t need to use USB to connect. Second, you dont need a large area to move around.

Very good option for me and worked well. Ergonomically a great fit and I hope to have it for a long time.

I wasn't sure what I was getting into when I purchased this, but after decades of using a mouse and hearing carpal tunnel horror stories, I decided it was a good idea to explore new options. I actually really love this thing. It takes a bit of getting used to, and a slightly different perspective - I kind of think of it as a two-step process of whipping the mouse cursor to the general area where I want it, because it has momentum/inertia, and then fine-tuning it to exactly where I want it. Definitely had to play around with speed settings for a while. Now this is like the only thing I use, I love it. Obviously, you are not going to use this for all tasks, especially not gaming, so keep that in mind.

I love these, they keep me coming back again and again.

I rework of the M570, overall its good, aesthetically an improvement, I did not test it but I feel the range improved slightly over previous unit (or my M570 could have lost range). Trackball movement however is not as smooth as older model. Still this is my favorite mouse/trackball device for Home Theater PC if within 10 ft of PC (use an extension to get better range - need to get transmitter away from PC's and TVs electromagnetic fields) and my favorite for using laptop in recliner (no flat surface needed)

I have used a trackball from Logitech for many years. It is nice that this one has a Bluetooth option.

This is easy to learn to use. The rollerball style is best for me because I was getting tennis elbow from all the mouses that I use. That is what my Medical Doctor told me about the pain in my arm.

Great Trackball faster than a mouse and more responsive.

Easy to use. I would for sure recommend this product.

I have been using these since 1990, wouldn't use any other.

Love it. Love it. Love it. Comfortable to use. Works great. Controls fit my hand well. Happy with purchase and would gladly purchase another.

Great mouse, scrolls very smooth. battery lasts months.

Works great right out of the box. Intuitive and comfortable.

I had one of these years ago when the ball was red. This one was not smooth. There is a weird feel to the ball, like it's grainy. I don't think it's supposed to feel that way. Other than that, the connection is good (fingers crossed it stays that way) I appreciate that this is bluetooth.

I have had to use these types of mice at work for about 15 years, because of carpel tunnel. Most people I know don’t like or can’t use these because they are not used to them. But for me they are a life saver. I have 2 of these, 1 for home and 1 for in office work. They work flawlessly, never had a problem.

Love it, blue tooth plus it has the unifying receiver as well
