Great for the first three months
I have owned this for six months and use it maybe once a week. Had you asked me to review this three months ago I would have given a favorable review. But just today I used it and noticed I could scrape my heel with my nail and scrape off dead skin. Additionally I've noticed it did nothing to reduce a callous I had. Overall I'd rather stick with my OPI foot file that requires manual filing.
