"Poor quality threaded tap connector, which leaks on both taps I tried it on, prevented this being a 4 or even 5 star review. The other parts do the job fine, so it was a shame that this one piece let the side down. As it is, its a significant flaw and a false economy."
"The two 'water stop' connectors in the pack I bought were so badly made that they disconnected from the male connector on my tap as soon as pressure was applied. The other female connectors were fine so I presume it's a manufacturing problem."
