it also depends on what you are runing off of it, or using it for, i myself have used one, only after we had all the christamas lights up and figured out it was the wrong plug so we improvised
you know how christmas lights have both the male and female ends, so you can connect them together in a long strand? well imagine putting all the light up with the wrong end at the outlet, it works but i won't use it but for lights
I just didn't understand why you would need two plugs connected lol. I was imagining someone plugging them both in at the same time... just couldn't make sense of it lol.
there really isn't a point just thought you all would get a good laugh from this contraption. He made it for his christmas tree light's cause he put them on wrong and the two end's needing plugged in where female so this is what he made.
