Review title is Works well, but frustrating lack of documentation [SEP] Local laws seem to vary regarding the use of shavers by pedicurists. Some places allow them, others don't. Since foot calluses are always an issue for me, a regular pedicure has long been necessary and I prefer places that use a shaver. But this gadget lets me take care of calluses myself quickly and easily, after a shower when my skin is soft. It works like a charm. However, there are no instructions and it will take you a little time to figure out how to use the shaver, how to use the rasp, and how to remove the blades (which need to be removed and cleaned after each use). This is a big negative. If the manufacturer added an instruction booklet with some diagrams then this would be a five star product. But it's worth struggling with it the first time - then you'll like it.
