well crap, I'll have to let them know to keep an eye on it, then.I know a fellow that bought some U ground male plugs from Princess that looked like Hubbell clones, except they were a carmel color instead of yellow. He discovered the connection clamp screws strip very easily, and the blades are loose enough that they can slide within the bulkhead insulator.
They weren't such a good deal when he tried to install one on an extension cord.
