Bought this from SmartHome to get free shipping on some other items not sold on Revain (or sold for big money) . lower price than Revain). A lot of my equipment (e.g. a fan) would not fit in this article. I called the manufacturer and they told me to use force to plug something into it. It worked for a couple of my devices but not others. All devices that should not be connected to this article can be easily connected to various sockets, adapters and extension cords. So I'm sending this adapter
