I thought that these might be a pretty good idea for the outlets in the nursery that need to have things plugged into them. Unfortunately, they don’t seem to work very well at all. I found that unless you tighten the plate down really hard, there is a gap between the plate and the wall that concerned me. When I did tighten it up, it had the problem that the plugs would stick open, rendering the plate entirely useless. Additionally, several of the plugs that I tried didn’t seat firmly, which means that there were exposed prongs. These are gone now and I've put in outlet plates that have a spring-slide cover. They don't seem like they need as much work to open, but at least they work.
