This extends you Fire Stick and gets it from behind your TV. The word Booster is a little misleading, it doesn't boost your WIFI , it only gets your Stick up so you can receive your WIFI signal better. I knew this before I bought the item. I would recommend this to everyone.
This is exactly what I wanted/needed. The extended that comes with the fire stick is sufficient if you want it to poke out on the side of the tv. With this you can actually extend it down so that it is not unsightly.
