The product itself is strange. It works without question and even good. From 500 come 150 - 250. Net, which is sufficient for video on demand, etc.! The question is simple ... How long do you think? I am glad that I bought this product on Amazon. I now have the third pair of these devices. In the beginning everything was great and easy to use. Wi-Fi with no problems and everything was great. After about 10-11 months then comes the first "Disconnection" (real data transfer about 8hrs / week) and from then on you go with me going. Time you can watch a movie, sometimes it breaks after an hour from, sometimes then every 5min terminations etc. I can fault due 100% to the unit, as in the whole house no changes were made. Etc. Not even a vacuum cleaner is turned on. Considering the equipment once out of the socket and plugged you re a good everything is back! Se Super devices and the function and configuration is very easy. Thanks Amazon with 36months warranty. Thus there is no risk but because of the short duration runtime only 4 stars
