Query: Weak Connector, again

First I tried it at the store with an opened box model. There was a screw missing which held the connector in place. It was found elsewhere, loose from where it should have held the connector in place.So the clerk got me a new one. I took it home and the small connector unit came loose. It appears the two screws that held the connector in were not screwed in completely. two different widgets, same conceptual problem.Quality control appears to be an issue.
