Customer Ratings & Reviews

This mouse is a perfect size for my big hand. And it gives my thumb something to do.

I got one for my computer at work. So more convenient and easy to use.

I have three of these and can’t use an ordinary mouse anymore. Love these things!

I love trackballs. I love wireless connections. This is the best of both.

We are enjoying the ease of use of this mouse. It makes our computer use so much better.

This is so much easier to use than regular mouse. Helps with hand getting aches.

This is one of the best trackballs out there. Love this product. Hope it never goes away

Love my mouse.. easy to use and install...........

Very easy and comfortable to use. I had Logitech trackballs before and always liked them.

very happy with easy use and dependability can put it on my leg and not have to move it and scrolls fast

I have been using an M570 since 2013 or so, and wore my last one out. The left click began to misfire after a few years, millions of clicks, and many drops. This trackball has proven its ability in gaming, browsing, and productivity. I have used many other mice, be they focused for the office or gaming, and I don't look forward to the day that I can't use this exact trackball.

At first this is an awkward mouse to use but after a couple days it was very clear; this is the most comfortable mouse I've ever used. This is actually a second one so I didn't have to keep moving it from system to system. A clear No-Brainer; just understand it is real awkward when transitioning from a standard configuration mouse to this.

I have carpal tunnel and this mouse really helps me.from aggravating my wrist!

I mouse ever! The ease of use is great and the comfort is amazing.

If your wrist hurts from moving a mouse all your desk, this has a good chance to helping the problem.

I love it this is my second track ball mouse to own and wouldn't go back to the normal kind

My favorite is the logitech trackman, which I have, but they don't make them anymore. This is the next best thing. I have one at work and one I use with my personal laptop, with the trackman being used on my personal desktop. I don't really notice a big difference between the two, other than the obvious wireless connection. Good for everyday use, though I use a regular mouse for gaming (I have a friend who games pretty darn well with the Marble trackball) For whatever reason a lot of people don't like trackballs. So it's a also a good way to keep people off of your computer ;)

Very easy to use. it replaced my wired trackball and has additional features to enhance the functions

I had a similar style that I used from r over ten years till it stopped working properly. It was great and d to find a replacement at a great price

Did not think my wife would like this mouse but she did. Great for the price.
