I was hugely skeptical whether this filing keeps its promises. So completely without screws and plugs.
Clear 33 kg are not in it, but even so a lot of weight, 2 bottles of bubble bath per 2 liters, several other bottles and keeps them on the wall.
We have smooth tiles that we have once freed carefully and remove grease, etc. (alcohol and microfibre cloth). Then have like using the paper template, supplied with the bracket attached to even just attach the tray. The large "syringe", which ensures that the vacuum generating beliegt.
The filing was to install quickly and easily. She is also well made. We like it too by design, simple and romantic park, with little corners and edges. They can be wiped off with a cloth afloat.
So far we are very satisfied, it will only show up in the long run, if the storage can remain truly rust-free.
