Excellent multifunction sander: several adaptive plateaus, silent, with electronic controller: it does a very good job. I recommend flat sanding tongue for sanding in hard to reach places. The irony is that the DIY stores (Leroy Merlin, Castorama, Bricorama) in my department do not know the product, yet not so recent as that. They do not want to order it and are unable to give you a prize! Thank you Amazon!
