Great product
My husband's heels are so tough and thick  and this thing seems to be a match for them. A LOT of skin came off when I only focused on his heel. I thought it may be particles from the sander part itself, but it seems to stay intact and is still very rough, so I'm sure it's his skin. After a couple of treatments, his heel is much softer. I also was able to get something out of his heel that has been in there for a long time. It would take a long time to do the entire foot, even both feet! I guess it's better that it's gentle and slow, but one will really have to work at it to get the whole foot smooth if it's in a really bad state. We will continue to use
