Bests & Worsts Reviews from Amazon

If there was a photo of the back of this outlet adapter, you would see that the bottom plug is just a "plastic guide" that slides into the wall for stability purposes, so ALL 6 plugs are powered by the TOP OUTLET ONLY. What this means is, that if you plug this adapter into an outlet in which the top half of your outlet is controlled by a light switch, the light switch will turn on and off ALL 6 plugs. Likewise, if your light switch controls the bottom half of your outlet, your light switch will become completely useless since it is only connected to the adapter's plastic guide. Other than that, these are not only great for neatly fitting many big transformers, but also make small plugs look much more "sleeker" by coming out of the sides and right up against the wall (vs. having all 6 plugs awkwardly sticking straight out). UPDATE: At the time of this review (3.5 years ago) there was no photo of the back of this unit. But someone has now posted a picture. As they say, "a picture is worth a thousand words". Nice photo, and thanks! I'll leave this review posted anyway, just in case the picture is someday removed.
