It is easy to use
I use this everyday and it takes me very little time to keep my feet in top condition. It is extremely reliable and I would give it 10 stars not 5! It is easy to use, no batteries to change. Just remember that you should use it in an area that is well ventilated and easy to clean.  I use it directly over a small waste basket to help keep the area clear of dust.
