I have tried everything from the brass to various plastic quick connects for garden hoses and they all either are next to impossible to connect while under full water pressure or they snap off within a few weeks of use. These so far have taken the abuse of daily use with multiple connects and disconnects per day without issue. They don't leak and are easy to connect and disconnect while under full water pressure. The hose end does not leak either when disconnected (I've found many other plastic ones do). I recommend these. I hope the keep lasting, so far these have lasted longer then every other plastic variation I've tried.
