I bought this to use when traveling internationally - simply plug it into the tv in my room and connect thru wifi - most of the countries I travel to have little to no English programming available with the exception of a few major news networks - and they get old very fast - so the Roku stick makes it simple for me to have a choice of movies - music - etc.....Small and light - easy to pack and priced well. I use my mobile for remote control so all I have to bring is the stick, cable and power supply.
We cut down on our Dish Network. Still kept the basic package for local channels and sports. The Roku has a lot of content and always adding more. Well worth it.
