Bought because my hose (which is about 2 months old so fairly new) was leaking at both the fitting where it connects to the water line and at the sprayer. I attached this to both ends and reattached to the line and spray nozzle and both are no longer leaking! I love it when an idea comes to me to fix something and it really works! While I don't really need 5 of these, I expect they will last for years and be handy. I'd rather overbuy and stay home than buy a roll and deal with parking and a receipt at the local hardware store. Every time I buy something online I always check reviews. I rely on others to help me choose the best option. My reviews are always my honest opinion and I try to include photos whenever possible.
