This child safety device for outlets has completely convinced us. It fits without Pobleme in our outlets, so that it seems to be totally uninteresting one "playing around" (it fills the socket completely out) and can be removed easily with a plug. The only downside, of course, if the child is able to pull the plug: the outlet is unprotected in front of him. However, that is a problem, what with us in many of the conventional backups to multiple use also was present, as they are no longer bound to their initial position.
