Bests & Worsts Reviews from Amazon

The unit arrived and appeared to be new. I set it up and it was easy. Started watching a movie and an hour later it lost the internet connection never to connect again. All my other items still worked on my internet, reset the router, that didnt make any difference. I bought the extended warranty and called Amazon for service (since they say on the item that tech support is included). There answer was to turn the unit off and on again, which I had already done. Then they had me restart the router, it didnt work. THEN they wanted me to call Roku to see if they could help. One of the reasons I bought it from Amazon was they said they would support the item. I demanded another unit, which they said they would ship. Then for some reason the tech said my address had been deactivated by Amazon WHAT?? I said, you shipped me two items today at that address. After refusing to give my credit card to the agent she said she talked to her supervisor and she had read her screen incorrectly. So I will see when I receive my next one if it works for more than one hour. This is an update. After researching the item I discovered it lost its MAC address. So no matter what I did it would not connect to anything. No luck from Roku support, that is a joke. I got an email from them asking if the problem is resolved. When I tried to answer the email it said my service ticket is closed. Really....
