The magnet was loose already after unpacking. With a little silicon I glued the magnet securely in the holder. The next day I cleaned the tile, degreased, stripped off the protective film and the holder mounted in our shower. Yesterday (after about one week) was the holder in the shower tray. Either our soap is too heavy or the tape was too weak. Today I have the double-sided adhesive tape is removed and the holder with silicone glued to the tile (remains secure until tomorrow with tape to prevent slipping.) As should now but hold. Conclusion: Not for people with two left hands or serious soaps. ;-)
