I have the Roku Streaming Stick in my bedroom and my Roku 3 in the front room and I love them both. The only thing I wish is that I could access my Facebook or Internet Explorer. But otherwise it is awesome not to be paying a big satellite/cable bill every month.
Sales people don't seem to understand what is required to use Roku. I have the most basic cable service and bought the stick and set it up. Apparently that isn't adequate to enable me to get the channels offered through Roku. After registering for a few and getting the message that I couldn't access them, I returned the Roku stick. I was very disappointed.
Worth it to buy. Toughest thing was getting package open. Easy installation and set up. Was going to buy a blue ray player to get Netflix when store clerk recommended Roku as I did not really need another DVD. It works great. Make sure u have a good internet signal near TV or get a booster.
