Fits well but make sure to use plumbing tape too
Fits my tap perfectly but even tightening the thread as much as possible didn't stop a small squirt of water with a mind of its own. I fitted the aerator and in my excitement turned it on full blast and a wayward stream soaked my girlfriend who was stood next to me. I found it hilarious but she was not impressed, so had to get the plumbing tape out. It works as it should now

Excellent.
New bathroom fitted. Tap had a strange helical flow which seemed to prevent pressure. Popped this on, hey presto ! a straight flow.

Cumplen con lo que anuncian. Reducir el gasto de agua.
Compré estos reductores-aireadores de agua porque a mis hijos les cuesta entender que no hace falta abrir los grifos al máximo para lavarse las manos o los dientes. Compré estos de marca ya que para mi Grohe siempre ha sido sinónimo de calidad y no me puedo quejar. Funcionan bien, reducen el caudal añadiendo burbujas de aire al chorro de agua, con lo que con menos agua tienes la misma presión, reduciéndose el consumo.

Très bon produit
produit de qualité, montage aisé juste avec une clé plate ou à molette. Les joints sont fournis. Le jet est agréable, l'économie d'eau est réelle. Quand on se lave les mains on sent moins la pression de l'eau, je trouve ça plus doux et agréable. Le débit est ralenti, on s'en rend compte lorsqu'on rempli une casserole d'eau, c'est plus long. Autre avantage, la tuyauterie subit moins les coups de béliers avec les enfants en bas age qui ferment le mitigeur trop vite.

Grohe Strahlregler top
Qualitätsware von Grohe👍Ich habe schon einige günstigere Strahlregler getestet, besser gesagt leider viel Geld verschwendet!!! Mit diesen 2 Strahlreglern ist alles absolut top👍👍👍Schnelle Montage, der Wasserstrahl ist kräftig und für ein Niederdrucksystem geeignet. Einfach alles richtig gut. Klare Empfehlung für dieses etwas teurere Markenprodukt das es wert ist😉
