Backs up the sockets reliably

By using these parental controls, the sockets are securely closed. The children are not likely to come in the holes with some small parts. There is no slowdown in tape, as with other socket guards.
In addition, the outlets were by these parental controls for our little ones totally uninteresting, because they "flatten" the sockets: the fuse in the socket, remains no "hole" in the wall, in which you can poke around. Other outlets with flatter fuses remained for our little ones, however interesting to poke at it with everything.
