it does not stick to surface [SEP] this product does clean your feet if you are coordinated but does not stick to bottom of tub if you have any texture on the bottom it will not stick it sticks to the side of my tub for storage without it sticking you have to use one foot to hold while trying to move your foot back and forth and that creates another problem the arch on the product gets in the way and you smack the bones in the top of your foot while trying to rub back and forth the pumous stone is terrible and gets in the way so trying to get your heel clean is tough and the stone ends up making the back of your heel rough the price was just too good to be true sorry
