EU to UK simple plug adapter.

Two models - one with just not sharp edges, another with more rounded edges

Caution. Never use these adapters with devices that are equipped with heating elements or any high powered devices.

NOTE: This is dangrous - it opens the protective shutters which protect the live terminals of the socket when there is no plug present. The Eurosocket itself is not very safe, but the holes are much smaller and no finger can enter (though a small metal object can), the live hole in a UK 13A socket, when the protective shutter is open, is large enough to admit a small child's finger.
