Detailing can get a bit like religion unfortunately.
Just of curiosity, I wanted to see if I could find something that would provide some sort of simple "professional" comparison of the various types of polishing machines.
The info, and video in particular, on this link from autogeek, one of the largest on line detailing suppliers that provides almost anything you would ever want for detailing (I have never used them, but they are very well known) is even better than what I was hoping to find; always something to learn.

Again, just trying to be helpful and ensure that folks make well informed decisions.... And to clarify, the Flex that I have, and have been referring to in my posts is the XC3401VRG; as you see in the video and on the auto geek web pages, Flex does make a rotary was well.....
