I have some pretty rough feet
I found that I was pleasantly surprised.  I have some pretty rough feet,  I am one who loves to go barefoot.  I didn't expect it to create miracles for me, but I definitely saw a big difference with just one use.  It did exactly what it is meant to do.  The roller becomes a little bogged down at times, I believe that is because I didn't give it a full 24 hour charge before using the first time.  That and it's meant to be used gently, I have a tendency to rush it.  When I take my time, it works great.  Too much pressure, shaving too much away at one time will cause a user problems.  It  removes the callus and it does it very well.  It works calluses down  without burning or feeling any pain.  It's certainly not going to solve a persons problem with one use, or over night, but it's a great little tool.  Over time, using this product, I believe my feet will be MUCH improved.  They are already DEFINITELY softer from use.
