3 stars only because a little disappointed at the reception. The sander was misplaced in his suitcase (which also comes in handy), and foam at the shoe was damaged. I have not bothered to send it back because it was not a major flaw, but in the end, I see that it is damaged.
After several months of use, a wooden staircase and a metal door fully sanded, I am still quite satisfied with my purchase.
Quite a few vibrations in use, which is nice for prolonged use. The dust bucket is fine, but only a flat use. In other cases, it is completely unnecessary.
