Water hose quick connect question

I use a number of them with my water hose and filter hookup. Always but the better brass ones, all the same brand. I tried to get the ones where I bought both parts at the same time. You are right, the cheaper ones will leak, but I have no problem with the ones I have. If I do have a small leak, just twist them a bit to reaseat, and the leak goes away.
To take them apart, be sure to turn water off, and release pressure in the hose or they will be very difficule to take apart, and will usually spray water on you.
