After purchasing this foot tool, I was thoroughly disappointed with its performance. As a beauty blogger, I was excited to test out its effectiveness but found it to be quite underwhelming.As a result of MY tests, I determined that it did not smoothly remove calluses and left my feet feeling rough and unfinished. The only pro is that the ceramic material felt sturdy, but unfortunately that did not make up for its lack of effectiveness. Save your money and invest in a better foot care tool..See full review
