The only reason I had purchased the Roku was for the NHL gamecenter they are the only device at this time supports that app at this time. Roku has issue's when you are looking for movies or going from app to app if you go to fast it locks up to unfreeze the unit you have to unplug it and wait then plug it back in. I have the Amazon Fire Stick on my other TV and don't have any problems at all and it is cheaper.
I really like that the unit is basically a thumb drive, fewer wires. I don't like the fact that after watching a movie, the unit automatically proceeds to another movie. If that could be disabled, I'd be pleased.
The free channels have commercials more frequently than television, then the shows take forever to start going again after the commercial. I got so I could watch Netflix on my TV. Sometimes that won't even load.
Easy to use and has great choice in apps. I am a time warner customer and use the stik, along with the tw app, in place of a box on one tv. This allows us to view on that television anything available to us on TW without having to 'rent' a box.
