I'm sure many of us who use Fire Sticks regularly experience more buffering than we'd like to because of Wi-Fi streaming. This product assumes Wi-Fi boost. Actual Wi-Fi gains will certainly see significantly less buffering, if any at all. Unfortunately, having watched a couple dozen movies since purchase, it doesn't seem to affect buffering in any way. It looks like it's just an HDMI cable. The price of this product was cheap but it doesn't really do what it offers so unfortunately I wouldn't recommend wasting money.
