Good test, thank you. Just few comments: Of course for Flex, backing pad must be screwed first into excenter nut and insert in machine, what you discovered in 09:55 :-). But I know that it was your first observation and test. Small backing pad (30 mm and not 1 inch) can be used with 12 mm excenter nut for polishing and not only with 3 mm for sanding. Same for bigger one 75 mm. In the set there is no 50 mm pad but you can buy it separately. I recommend it. Flex is not only polisher but sander too. You have right, due to size and weight it´s not powerful as others but if you will use microfibre or wool pads, it will cut much better of course. Keep continue, good job and nice day.
