Review (1/5): Slippery. Brace yourself.
I guess if you are laying down in the tub and scrubbing then it might work, no, it still wouldn't. The problem I had was while the suctions were firmly stuck to the tub floor, the entire product slid and scooted around the tub. So it was ridiculously difficult to unsuction it from the floor after showering, but the darn thing moved when trying to scrub the heel. I got this product for my mom, because a chiropractor suggested it for the stimulation to the feet for elderly who are unable to bend down. I guess it sort of scrubbed the top of my foot a little, but it did absolutely nothing for the heel, the gnarly part that actually needs the scrubbing, since it moved so much. I asked my mom what she thought and she said "definitely not enough strength to get any real stimulation from it."
It's also ginormous to have in the bath.
