+ Extremely strong hold on all load-bearing surfaces, such as tiles, natural stone, concrete, wood, plastic
+ Permanently high loads (up to 80 kg per fastener) and removed without leaving any
Sounds kind of too good to be true. I did not want to drill in flow, but also not buy Standklorollenhalter. That's why I gave the product a chance.
Now, after two years, I can not and will have to confirm the advertising promises. After cleaning the flow I as described in the manual at all just fixed this. After the specified drying time, the thing holds bombproof. The einache replace the toilet paper roll is another advantage of this system.
Conclusion: Even after two years, secure hold and no rust or the like. Buy recommendation on my part!
