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 was skeptical but for the price I was willing to take a chance. I noticed putting it closer to my router made a significant difference in the reduction of my previous buffering problem. Likely faster than an Ethernet adapter. Good buy.
