## Customer Reviews

### ⭐⭐⭐⭐⭐ Using as a 3/4 hose to tap connector.
*by M***. on 18 August 2025*

Very reassuring fitting.I do love these Gardena fittings, they feel solid and a fine permanent install.Certainly not a quick release but just easy enough that it isn't the end of the world if something goes wrong they can unscrew by hand and clamping the hose is easy enough.Due to bulk of them it maybe slightly tight if your tap is abnormally close to the wall.So far no leaks, and very reassuring fit.. cheap enough too.

### ⭐⭐⭐⭐⭐ Works
*by W***E on 2 March 2025*

Just works. But obviously it is an expensive system to get into!

### ⭐⭐⭐⭐⭐ Easy connections for gardens.
*by B***K on 11 August 2025*

Does the job in the easiest version possible. No struggles and to use it is as easy as it could be
