Dang Gary! u one rich mofo to buy this stuff. Maybe for the old and decrepit, it's worth the cost to be able to disconnect a hose. A pair of pliers is free and just as good if you have a pair handy. Let's add senile. You forget everything including pliers so built in is a great benefit. LOLedit - if you get kickbacks sorry to the comment. Buy 6, one for everything and a couple spares!
I have one of these and love it.
I have one of those. I love it because I don’t have to fetch the channelocks. It also seems to have slightly loose female threads to mate up with boogered threads on the hose bib. I have used it for about five years and we do 60 campgrounds a year.
