Review (4/5): my brush heads fall. off
not very tight for my body brush (what i use). head falls off when not holding it face up.
UPDATE! I was offered a second one and this one fits better. I will glue it in place cause i have 6 different brushes and only need the large heads rly. The feet things, well pumice stones do nothing unless u spend an hour on a small area and there isnt much control at this speed. My father uses a hardware grater of sorts, for feet id go that route and will try myself
