Qualitatively, the hose coupling with security well. Good material and meticulously crafted, but not thought through. You can connect a 1/2 "and 3/4" hose - that sounds good - but only at first glance, since the flow inside the hose coupling is limited to 1/2 "hose diameter.
So if a 3/4 "hose wants to use due to the larger cross-section, which can actually nothing to do with this part because the connection here as" serve throttle ".
I would not buy this hose coupling, although it looks really great and is also processed dibasic.
