I've used these for years, they tend to stop working in 4 to 5 years. The price has gone up, but I guess everything else has. Make sure you take them off your outside faucets, due to they will freeze.
They work for me and I hope they do a good job for you
I'm using them a lot during the hot weather so I can water and go do something like sleep. I do have to clean the screen quite often because of the Irrigation water. It keeps the sprinklers clean. If you use them to couple hoses together I would recommend putting a hose water shut off before the timer to clean the screens without going back to the valve each time.
