This product really works. I usually don't write these goofy reviews but I'm thinking this might help somebody. For a long time I was frustrated with having to use wi-fi with the firestick because of buffering issues. Buffering while watching a movie is like getting a haircut and the barber stops just to start talking about sports. So I got nervous when I first tried it with my 1st generation firestick and it didn't work. So word to the wise it isn't compatible with the 1st generation firesticks. However I do have another firestick which is a 2nd generation and it worked like a charm! I was able to use a 75 foot ethernet cable from the firestick in my bedroom to the modem in the middle of the house in the kitchen. Its working great. So if anybody is wondering, stop wondering if you want a stable connection with your firestick but just remember, 2nd generation and up!
