I haven’t tried one for polishing but I did a short demo for sanding. It’s an impressive tool, very well made (like all Festo tools), nicely balanced and very powerful. The difference in aggressiveness (for sanding anyway) between RO mode and driven orbit mode is outrageous.
I didn’t buy it because, at the time, my regular abrasives supplier didn’t have disks for them. If I had I’d definitely give it whirl for polishing.
