Query: Outlet Plug Review

These plugs worked well for me for a while. My 2 year old has somehow figured out how to dislodge some of them from the wall. I do not know how in the world he does it as some of them do not want to easily come out when I pull on them. It could be an outlet issue as well. For the most part they stay in place and do their job. I'm assuming that their might be something off with an occasional plug in the packages that might make them easier to pull off.I would say for the most part they are properly manufactured and safe to use.
