Among Chinese manufacturers, it's very common to share molds.

A lot of the "cube taps", grounding "cheater" adapters, extension cords, etc. I see in our local stores look cosmetically similar.

To notice differences, you have to pay attention usually to the manufacturer's model number or UL file number (if there is one).

Sometimes the manufacturers actually do put their names and logos (Yun, Feng Sheng, San Shih, King Tec) on their stuff.

Maybe one of thse days I'll do a little "line up" and take pictures of them so you can see what I'm talking about.

God, I'm such a GEEK! [Linked Image]
