Within a short time after more than three decades, two plastic hooks in the bathroom and in the kitchen had broken away from the tiles. I was looking for just such hooks and was, as almost always, find it at Amazon. I have, as recommended, the residues of the old hook removed, press the hook on the tiles and not charged for twelve hours. Then I hung up again my brushes bag in the bathroom and the potholders on in the kitchen over the stove on the hook. The new hook again make a very strong impression and I hope that they are made to last, and I am convinced.
