Customer Ratings & Reviews

This mouse works great and can be used on the arm of the couch, on your lap, or when leaning back in a recliner, on your left shoulder. You won't be limited by a pad or flat surface. I love it.

Easy for people with carpal tunnel. Takes a minute to get use to not move your mouse around and just move the ball. Once you master the ball you will love it.

Precise control without having to move all over the desk.

Good trackball, but after a while the one button will begin to double click and it’s time for replacement.

This trackball has worked perfectly for my husband with his laptop. We have had many trackballs and that is the only type of mouse he can use easily with his laptop. The battery seems to be holding up good so far.

I always liked roller ball mice. This one works smoothly.

I have 3 of these, one for my home desktop, one for my personal laptop and one for my work laptop. It's ergonomic and comfortable, but only if you are a right hander. If you are left handed it's awkward to use.

While this mouse may take some getting used to I LOVE it. It remains stationary and only requires a little thumb movement. No need for a mouse pad whatsoever. I would never consider using a 'traditional' mouse!

I finally had to replace my original M570 after many years. The scroll wheel finally gave up. I love it so much I didn't even research...just purchased another one.This type mouse is so much easier on your hands.

Great for the limited space on the Home Theatre computer.

I am a fan of using a trackball mouse over a regular one. I love the wireless on this, as it makes it much easier to work from wherever I need to with it. Works great, no problems!

My only problem is the ball wears out after about a year.

I love this wireless mouse. Easy to use, and it is efficient

Affordable, good quality and definitely good if your wrist hurts from you traditional mouse. However it is a huge learning curve but once you get used to it, it's amazing. Be patient.

Using a track ball mouse saves your wrist and arm from all at moving around the Desk. Gives more space especially if your Desk is small. No carpel tunnel for this guy. Easy operation without the hassle of wires

Needed a wireless trackball and this had good reviews...

Had a problem getting used to using this particular Model

Due to metacarpal surgery on both wrists and ball tracking mouse is what I need. This fits the bill. There is a slight lose of tracking now and then (the reason for only 4 stars), but otherwise performs flawlessly. Wireless big plus. I have not checked what I can assign to the buttons on tracking yet.

Easy to use... comfortable, stylish, modern... i used to design using bigger trackballs back in the days... this is a great improvement at my pc desk...

Good mouse for daily computing tasks or for gaming. There is a learning curve but once you learn how to use it you will like it a lot. I use the back and forward page buttons when I am browsing web pages.
