Finally something that works!
I LOVE this product! I have (embarrassingly) dry and cracked heels.  In the summer I would have to spend time every week filing with a course, medium and fine file to get my heels to a place where I wasn't embarrassed to wear flip flops.  Even then, it wasn't how I really wanted my heels.  After one of the files I used was discontinued I decided to look for something else.  I decided that I wanted something with a motor that would really get the job done.  Most of the products I found had mediocre to bad reviews until I found this one.  I decided to give it a try.  Now that I have it I don't think I'll even use a foot file again!  It is very easy to use and works to file the skin away with ease.  I love the adjustable speed.  I keep it about a third of the way up.  The first time I used it (with the course disc) I had the speed set higher and my skin became very warm and felt like it was burning to I turned it down to a slower speed.  The fine disc I can use at a higher speed.  I can file my feel in a few minutes and they look and feel great.  I have used it 4 times so far and both of the discs seem like new, so I suspect that I won't need to buy refills for a while.  The only suggestion I have it to start at a slow speed and get used to it before using higher speeds to see what you find comfortable and effective the first couple time.
