As I see with many other reviews, the hose connected to the female plug comes off rather frequently.  I only just hooked mine up today (the day after it arrived) and it blew right out.  There are two half circle metal pieces that fit into each tube and then,once folded into a full circle should fit snugly into the female hose end.  It does.  And I was able to repair it myself with no tools or glue (but time I could have used more productively elsewhere).  It still leaks a little, but it's serviceable.  Also, the brass hose connector is very shallow.  It would not fit on my male piece which was plastic.  I eventually found a different hose end that it did fit on.  I thought about contacting the company, but surely by now, with all the negative reviews surrounding this particular defect, if they were interested in either quality control or customer service, I believe I would have seen responses in the review section.  If I missed those responses, forgive me.
