## Customer Reviews

### ⭐⭐⭐⭐⭐ Gutes Produkt
*by  on Reviewed in Germany 3 October 2018*

Nachdem mein Einkaufversuch im Baumarkt gescheitert ist, habe ich bestellt. Die Lieferung der Dichtung, offenbar eine britische, erfolgte schnell. Die Dichtung war im Eimer mit einer Flüssigkeit betreufelt, die das Produkt feucht und geschmeidig gehalten hat. Sie hat gut in die Nuten der PVC-Terrassentüren gepasst. Der Einbau war einfach und ging wesentlich schneller als die 19 Jahre alte "Dichtung" auszubauen. Ich werde mehr bestellen.

### ⭐⭐⭐⭐⭐ joint pour fenêtre et portes

Mieux que les joints autocollants qui se décollent dans le tempsFacile à poser, j'avais des portes et fenêtres avec rigole de 3.5 et 4.5 mmLe produit est livré dans un seau en plastique bien fermé ( pas facile à ouvrir ), les joints sont lubrifiés, pas besoin d'utiliser du liquide vaisselle pour faire pénétrer dans la rigole du PVCLe joint est souple, et épouse bien les anglesseul reproche que je pourrais faire, c'est qu'il n'existe qu'en noir
