Logitech Trackball Mouse
For me, trackball mice have been the best thing ever for 20 years.
It takes a little getting used to, but then you don't want anything else.
Pro
- everything can be done with thumb and index finger
- Easy on the wrist
Contra
- trackball has to be cleaned from time to time incl. the sensor contacts
