I think that it would be fair to say that the reviews of this product have been mixed. As some reviews indicated that the product was dangerous, it was with some trepidation that it was ordered. However, having now received and fitted the product entirely satisfactorily I am a loss to understand some of the other oomments. This is a device that is intended to enable a lead terminating in a continental type 2 pin plug to be inserted safely into a UK 13 amp 3 pin socket. On opening up the cover, 2 clips are revealed that accept the pins of the continental plug. Once the pins are pushed firmly into the clips, the cover is closed, the retaining screw tightened and the continental plug is retained safely and securely within the body of the converter plug. It is a good product at a reasonable price that does its job well.
