I ordered this product because I needed a polarized UK plug adapter. I was charged 7.25 for shipping but the plugs only cost 1.85 to ship to me, which is a total ripoff. Even worse, when I attempted to plug anything into the adapters it fell right out! Nothing will stay plugged into them, so they aren't even usable. They are not the plugs pictured here, they are much cheaper and don't work. Don't bother buying these adapters.
