We had a stick-instead-drilling variant of Wenko mounted in the bathroom, the secure hold itself vanished after about four months. Whether it was due to the moisture or heat in the shower to be seen, other Wenko products with the adhesive pads (in the bathroom, but not directly in the shower) hold already bombproof in many months. I was a bit skeptical that a vacuum can be on the tiles, which are not as smooth as glass, produced at all. The supplied small pump initially acts as little reassuring, more like a child's toy, but see: The shelf snugly and securely to the wall. Loaded it with two shower gel, a shampoo, two wet razors, a can of shaving cream and two sponges. This is certainly not a ton load, but with the weight of the shelf but noticeably. Whether the attachment loosens after a few months remains to be seen. Anyway, would it, if it occurs, by the vacuum pump, a slightly correctable defect, while the rebonding of the adhesive pad-Vatiante, was successful only for a few days, not even weeks with us. My conclusion: Who does not want to drill and is not happy with the bond, it should try with the Vacuum-Loc variant.
