I am 58, male. Have been a Cosmetologist since 1976. Have tried many foot tools. This one is the best yet,,, except for the angled handle. What was the designer thinking. It makes it difficult to use both sides of the tool equally. I live in the desert and ware sandals 325 days a year. This tool quickly removes any ruff or road stained skin with the course side and then smooths the skin with the fine side. When I first looked at it, I thought the course side would be to extreme, but it is not. Just remove the angled handle and it will be perfect.
