Easy to set up, easy to switch between two computers, the screen display is excellent. Just to report one issue, if the screen resolution set on both computers is not the same, the window of the computer set to the lower resolution will change every time you switch to that computer. A computer that sets a higher resolution does not suffer from this problem. This is a very annoying problem as not all computers can be set to the maximum screen resolution. In my case, one is almost new and the other is almost 10 years old. So in my case it is a one star product. If your two computers have the same screen resolution, it's very good for you: 5 stars. So I averaged two.
