Let me start with admitting my biases: 1) I read all the bad reviews, so I had extremely low expectations, 2) I have huge feet (size 14). I contrasted it and compared it with similar products, but this was the only one I could find that could do the main things I wanted: A) Get between my toes (hard to do even by hand!) and B) Get the tops of my feet, too. All the other products I saw only got the bottom of the feet. Found it on sale for $7 and free shipping when I added it to another order, so I figured I'd give it a try. Been using it for a couple weeks now, and I love it! Yes, it does slide a little, but not much if you use common sense (and have a large foot); you're not supposed to put your weight this, you put your weight on your back foot and slide the other one in to wash it. It scrubs my feet great and better than I could do it by hand. Now I said scrub, which I need, but someone with more sensitive feet may find it a little harsh. No more toe jam! And the bonus? Due to the pumice stone, the 20-year-old callouses on my heels were gone within a week or two! I'm so glad I got this, it was definitely a bargain, but maybe I don't expect that much for $7.
