Seems to fit nicely into a 'regular' socket but two prongs (a ground and a plastic prong) don't fit perfectly into a GFCI socket - the pins are there friend too close together. The result is a device that tries to slip out of the socket no matter how hard you try to hold it. In a vertical arrangement without heavy plugs with sockets, cutting the plastic pin will probably work.
