I was unable to use all of the item's outlets. Many of my devices (such as a fan) would not fit into this item. I called the manufacturer and was told to use some force in order to plug things into it. This worked for a couple of my devices, but not for others. All of the devices that would not plug into this item, plug in with no problem into various other outlets, adapters, and extension cords. So I'm returning this adapter.
