it is quiet not super powerful [SEP] i do like that the different grit rollers can be flipped right on the head it is quiet i charged it several hours before using it but it began lagging quickly i plugged it in and kept using it and did not notice much difference while plugged in the description recommend only use or seconds at a time but i did not find any reason why it would say that it was not very powerful but i did see a considerable amount of very fine skin it did not collect in the little tray that i could tell it claims to work wet or dry i will leave the wet testing to someone with less candles on their cake than i my feet felt better after usingi believe there are better ones than this at a competitive price point it did work so i have to give it at least it was quiet so that is a plus the charge cord is very short
