It works perfectly and I am very, very happy with it - easy to use fast and oodles of channels to choose from.
I decided to get a second device and rather tan sticking to what was working, I fell under the spell of Apple and the hype around it and purchased an Apple TV 2012.
What a disappointment!! Difficult to connect to the same Samsung TV that I had no problem connecting to with the Roku. Eventually I managed to get it linked to A LG TV. I battled to get the remote working properly and then found the channels that were available to be very limited, compared to the Roku. It also appears to be much slower than the Roku.
If I can get rid of it I will and will definitely stick to Roku!!
