Query: manufactured to be defective

I have rarely bought a product so defective by design as this one - which I deliberately selected to get a metal (instead of plastic) spray rood. On no fewer than three locations, the "want" wobbles and when not stay screwed in or fastened for more then 20-30 seconds, and, even when fastened, leaks at any given time on at least one of the three locations. It's not just the lousy quality control of this junk, it's that any company would actually believe it can sell something this bad. It's planned obscelence - from right out of the box. I don't understand the other positive reviews. It doesn't look to me as as if I just got a sprayer that was, by way of exception, defective, but rather that the entire design/manufacturing is seriously faulty - across the board.
