Review title is Best I have used [SEP] I have used many different foot files and this is the best.  Use it with the Footkogix callous remover and it really works.  I have old, cracked heels from years of going bare foot.  Weekly pedicures are too expensive but I need them.  Not anymore.  I especially like that I can sanitize and reuse this file.  A bit expensive but worth it.
