The problem with plugging things into outlets is that while it’s super easy to plug things in, unplugging things is not as easy. Ok admittedly it’s not as big of a problem as say world hunger or Windows BSODs but it’s a minor annoyance. Sometimes those plugs just don’t want to come out of the outlets- you have to jiggle and fight with them to get them out smoothly. Well the plug with a hole concept makes it super easy to remove the plug because it has a hole for your finger. Ideal for that one gadget that you are constantly plugging and unplugging.
