So I bought this larger pack due to the fact I have a lot of items that I use my garden hose on and wanted to make sure I had plenty to go around. I didn’t want to have to keep changing them from item to item. Now I’m going to buy another pack because they work so well.I have 3 hose bibs on my house. I also have a fresh water hose in my RV as well as a tank flush system. This pack comes with 2 ends for a hose and 4 for items connected to the hose.It is really nice to quickly connect and disconnect the hose but it really makes it nice to do this task without having to shut down the water every time. Kink the hose and just pop it off. You don’t gat wet. Quick and easy.It is also nice to have these on the RV as it make for a simple and quick connection especially for the tank flush. Connecting and disconnecting the hose in a tiny recessed box on the side of the RV is a real pain.It is true they do not leak. I haven’t had them for too long and I suppose if you left them connected together for a long time the gasket could get a permanent groove in it and it may eventually leak. They do however send along two additional replacement gaskets or washers.The items seems very well made and sturdy. The male end is on the items connected to the hose so you’re not dragging that exposed end on the concrete and marring it up which would ultimately lead to a leak. The female ens connected to the hose end has nice plastic/rubber pieces for cushion/protection if dropPed on the ground as well as a nice bit of grip when actuating the quick release.I am very pleased with these items. As I stated earlier, I will be buying more.
