The trackball has always been my favorite pointing device and I have never had a wireless one until now. The Logitech m570 is the coolest one yet. With forward and back buttons , wheel scrolling and thumb ball all at my finger tips its quite a pleasure. And dealing with Overstock was a pleasure.
I had been waiting for a wireless version of this trackball since I loved the old wired version but the wire gets in the way. This also works great with my Logitech keyboard because I only need a single usb port for the receiver. Good deal at Overstock.com as well!
I love it! Works like a charm. I have arthritis in my hands and this trackball is perfect for me. Easy to use and doesn't cause as much stiffness in my hand as a regular mouse.
