Review title is VERY STRONG but works fast with short/gentle touch [SEP] Tried it last night after shower and it worked wonderfully. It is TRUE that this spinner is REALLY strong, I was trying with the black sanding pad (the rougher one), even at the lowest power I can feel my skin is burning if I left it longer than 2 seconds! So I just used the white pad (less rough) with the lowest setting, making sure each contact is gentle or short. My dry feet were cleaned within 2 minutes, put on some coconut oil and I am ready to wear sandals. Will give it a few more tries in coming months to see if the machinery is in good shape, but the box says it comes with 3 years of warrantee, so I am not too worried about it.
