Review on Renewed Logitech MX ERGO Advanced Wireless Trackball for Windows PC and Mac by Hayden Hanson ᠌

The device is an amateur, you need to get used to it. If you have tremor, it will be more difficult to control the pointer than when using a mouse. The weak inertia of the trackball, in my opinion, is a disadvantage, an increase in mass would increase controllability by reducing random fluctuations in the position of the finger. I did not notice the work of the function of enabling increased pointer precision, this is not enough. Drawio does not understand the zoom function when using this device - the scale flies away. Perhaps this is due to the smooth scrolling feature.
