Other toilet seats had recorded the first defect after a much shorter time. That's not the case here.
The manufacturer promises a 10 year warranty. This he does certainly not without reason. We are completely satisfied with the Toilttensitzen.
Must plan places one certainly not, to the Matrerial is too thin and would certainly not without damage.
I can not find anything negative to these toilet seats. Therefore full marks and my recommendation. 5 Stars.
