My 10 year old son has severe autism. He seems to have a real problem with the sockets. I don't know why he doesn't like connected devices, but he really cares about connected devices, so he goes around the house turning off the TVs while they're on. He spent the summer shutting down mobile air. air conditioners. I was very concerned that it would break our electronics if I kept unplugging them while working so I need to come up with a solution and as these plug ins are so big for such items especially air conditioners I needed a larger plug. into something just a normal baby test. These worked! He doesn't know how to meet her, which means he eventually gives up. Installation was as easy as installing an outlet cover. I think it also helps that when the plugins aren't visible, they kind of slip out of my head. In any case, I would be grateful if it weren't for the broken televisions!
