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.
I bought 4 firesticks for and bought 4 of these "WiFi Signal Booster for Faster Streaming" things. They do NOT BOOST anything!! It is simply an extention for firestick cord. If i coluld give it less than one star I would. Completely false advertisment. And to top it off when I tried to return them they "are not eligible for return". I only opened one of them (gently) and the other 3 are still sealed. Why can't I return these? not good business :( I LOVE amazon but this is not cool.
