For Duravit original, many people have complained and suspected that at Duravit the break "By design here is virtually a break-installed: The rear buffer are not on the ceramic, but hanging in the air sitting at old this was up to. 1cm, with the new 4mm. "
I suspect very strongly that with me as a design reasons here is almost a built rupture because it happened exactly the same to me, broken links, incomprehensible ... and with me this part was not right on it.
Now Presalit. And found that it was the wrong part is also here on the ceramic. it wobbles a bit already determined (estimated) about 3-4 mm difference.
Here But 10-year warranty are promised, I keep the pieces and hope that it can withstand 10 years.
