I bought this for my angle polisher sedan, so far I have been twice polished my car with it and am very pleasantly surprised, as the unit was very reasonably priced. One can continuously adjusted from 1000 rev / min to 3500 rev / min in steps of 100, display on the screen looks good, what I've brought were other essays with Velcro, because the enclosed my opinion are too big, I have brought from Wolfcraft the polishing wheel 125mm with 16mm thread. All in all a very good buy that. Machine has enough power and is never overtaxed or not overheated, even after long use, very clear Kaufemfehlung!
