I purchased this simply because I wanted to try a trackball. It is now my most-used input device. It is very comfortable, moreso than most traditional mice. Part of this is due to the shape of the trackball, but the fact that the hand stays stationary is also a factor.

- Excellent battery life (2 months and counting!; - Very comfortable

- Limited performance compared to some "regular" mice; - Poor scroll wheel

I have been using trackballs for over 30 years. I have 2 of these, one for home one for work. The one at home I've had for 9 years and just recently required replacing. I was pleased to be able to get the same model again.

If you need a comfortable trackball that has a powerful 2.4GHz signal for your tight and small workspace or desk, the Logitech Wireless Trackball M570 is perfect!

Comfortable; 80- 18 months battery life; 30 ft powerful 2.4 Ghz signal

A must-have for people who have difficulty in finding the space for a normal mouse. Extremely easy to set up and use. Works just as well as a mouse.

I have been using this Trackball for years. I have one for my laptop, my desktops at home and work. I find it very ergonomic and natural to use. It took a day to get used to not moving the unit like a mouse, but now it is perfect.

Mouse is super lightweight and does not feel/seem premium... hence the price. I do have some concerns about the small pads on the bottom that keep you from sliding the mouse: until you get used to a trackball, you will naturally try to slide it around like a laser one; and the small pads may come...

I have used the Logitech trackball devices in all their incarnations from the very first up to this newest version. They have all been great products that have only improved with each iteration. The ease of use, and the lack of wrist movement make the trackball a great choice.

Awesome mouse! You don't need a lot of space for this one, since it's not the average type mouse that you have to move all over. All you do is click and move the roller ball, so simple! I will admit it took a little getting used to at first, but now, I love it!

It's biggervthan I expected but as soon as I used it, my wrist and hand were relieved from the usual pain caused by holding a traditional mouse. If it was a bit less bulky it would be a 5star product.

If your service has always been and will be like this I am impressed. My first shopping experience with you has been very satisfying. I expect to shop from you again soon.
