This travel plug from Pure² helped me in Kenya. It is extremely rugged and very reliable - no problems there. For other travel plugs to read again and again that when pulling out of the socket, the lower part remains exposed and the power contacts. This can not happen with this plug, because the two parts are properly screwed together with two bolts.
The complained in other reviews CE mark is present on the packaging.
I recommend with changing accommodation in the destination country the purchase of 2 travel plugs. In my first hotel, I unfortunately can put a travel plug in the socket, and at the final check of the room to me is not noticed.
