USB2.0 Wireless Finger Handheld Mouse Mice Trackball Mouse for Laptop PC

This works great. More impressed with the quality. What a great design and you don't need desk space to operate. Bought for my 87 year old father because his hands shakes and can't use a regular mouse.

I have carpal tunnel and arthritis. Could no longer use a conventional mouse. This thing is a wonderment. A little bit of a learning curve. A little adjustment of your mouse properties and the cursor speed adjustment on the mouse and you're good to go.

Update: Been using this now for the last few weeks, my carpal tunnel pain has decreased by 80%.

Trackball sensitive and precise I cant say anything bad about it. Ball movement super smooth and is very comfortable to use.
