Bests & Worsts Reviews from Amazon

This beats a pumice stone x100! I use on damp feet after shower, put lotion on and wear socks for a bit to absorb the lotion. My feet stay smooth for days. I only have to use this about twice a week. UPDATE 5/11/21...seller did not give me the offered promotion. Furthermore and more importantly, after using this for a while now I find that the skin on my feet is beginning to stand up and feel almost prickly. It's hard to describe, but it's unpleasant and I have stopped using the product. Another update 6/14/20...seller has emailed me 2x asking me to delete my review. They offered me a $10 credit to delete my review. I am deducting another star. Asking a customer to delete a negative review is morally wrong. I have explained to the person contacting me that it is unfair to customers to only see positive reviews if there are negative things about the product.
