I bought the hook to guest towels or normal small towels (200 g dry weight) hang in the bathroom. The tiles were smooth and have been thoroughly cleaned. I have two attached by hooks to guide and even hang overnight without towel weight, because I thought that I was then on the safe side. Then I hung off the towels and was satisfied. After a few hours, but then came a hook from the wall and after about 24 hours of the Other. I still have a couple of times they tried again dranzukleben and tried it out with top button for more or leave two nights hanging with no weight, but apparently I do not like the system Tesa. I am now switched to sucker-hook from Fackelmann. The function properly and are even more favorable. Unfortunately, only one point, because it simply does not work.
