I don't know that much about it, but it seemed like plucking multiple hairs at the same time using a piece of thread when I looked into it.

From what I can tell, the main advantage seems to be in generating really straight lines and the amount of control.

Never done it myself, but I believe one of the other advantages (or maybe the actual reason for the straight line effect you mentioned ), is that it gets the very small fine hairs that you can barely see, let alone grab with tweezers, but they are what creates a fuzzy look overall.

This sounds very likely, Pansy-Mae. The devil is always in the details. huh?
