When now the new Vacuum-Loc system I have the suction cup is no longer in full force push against the tile but slightly press the button and then suck the air with an included pump. 33 kg is one of the two vacuum-Loc managed to hold, I burden the basket with a maximum of 6 kg, and he holds to date.
I mounted the basket in the shower. I'm curious how resistant the Vacuum-Loc's and the cage of steel (not stainless steel) in the shower area are and fill up here later.
