I thought, I'll buy time not with me at the hardware store ... what can you do already wrong at an angle connector purchase on Amazon. Use the product in a self-made extension cords, so it is now and then sometimes on and unplugged, but not far from exessiv. I figured now firmly after about 2 months ago that one of the contacts was bent inward. In addition, was one shorter than the other. When opening showed that the thin plastic began to crack in several places and the contacts from the plastic holder slid towards the interior. My solution was to drown both contacts in hot glue and hoped that the whole still holds out for a while. But my expectation was of course another.
