GREAT PRODUCT
This product is amazing.  I shattered my ankle a long time ago but because of that when I learned to walk again I evidently walk funny on my foot which caused a horrible callous on the bottom of my foot.  I have been dealing with it for years and was thrilled when the foot eggs came out.  The egg doesn't hole a candle to this handy machine.  I am using it about every 2 days so hopefully can get rid of the callous all together.  It is so nice not to have to worry about having extra batteries with you when you travel.  I ordered extra replacement rollers, extra course and extreme course for this summer when my husband needs to use it.  I would recommend this to anyone who loves to have nice smooth feet.
