Ummm, my personal opinion is that if you need this product, buy it. It's at your discretion. If you have large, painful callouses on your feet, you will most likely benefit from this product. I used to play a lot of ice hockey and developed large callouses on my feet, and I have found that a pumice stone is a quite lengthy operation to undertake. I was interested in the pedi-egg upon seeing it because it looks simpler to use and looks like it's much more effective at quickly removing dead skin. To the people that think this product is disgusting: if you're buying one of these to remove unsightly and painful callouses from the bottoms of your feet, that's really no different than a woman shaving her legs to remove unwanted hair or someone using proactive to decrease the layers of oil on their body... Grow up. Shit.
