First impression
Since this is my first purchase of this type product I really have nothing to compare it too....It does make my face feel cleaner and much smoother after using it.  I think the attachments would rotate a bit faster and I did try the pumice stone on my calluses....didn't seem to do much for them.  It is compact and easy to use though so that is nice.  Of course this wasn't an expensive set so I don't know if using something more expensive would be any different.
