Yesterday, I received it and tried it first time. I soaked my feet in the solution of sea salt and baking soda and after that I so much surprised to see how much dead skin was coming off with just a few gentle strokes. Look at the pictures. And I didn't even try my callus remover gel which I bought and was planning to apply next. I realized for the first use it is enough or it could be too much and I could get sore.I had inferior products before like pumice stone, etc. that did nothing in comparison. This is durable, well thought of, thoroughly researched and designed with best attempts to satisfy a customer product. Gush, how I even lived without it all this years. I can feel how my feet are breathing now! It is so worth those several extra bucks you spend to avoid the disappointment of buying inferior quality junk.
