My children gave me the Roku stick for Christmas, and I have been enjoying it ever since. I have to use the TV speakers instead of the sound system, which is not good, but the picture is great. I enjoy watching movies on Netflix, Amazon, etc.
WE have a Roku 3 and a Stick, the stick is great! It's hid behind the TV out of sight and the picture looks just as good as the bigger Roku! One complaint is that it does have to be powered. Not a biggie but another cord to run to the TV.
I love the variety of channels you get with the Roku. I have convinced all of my family members to get one and, of course, they enjoy it as much as I do.
