It stuck very well on the tiles outside the tub, but not on the ones inside the shower/tub.  I cleaned the tiles with everything from A to Z and no matter what they stuck for a few seconds and then slid.  I need these for myself and would not trust  them. The one outside the tub, on tiles that have always been dry...it is still stuck tight.
