I recently bought my second Roku streaming stick. Now I have one each for the family room and master bedroom TVs. I originally started with a Roku 2 but after a couple of years bought a stick and then another stick a year later because I liked it so much. On my 42" inch TV, I was initially had some buffering but that fixed that right away by plugging it into the wall socket instead of TV. But on my smaller TV, it's plugged directly into the TV without any buffering issues. I love the flexibility of moving the stick to different TV's if you want and the fact that there's no box sitting on the TV cabinet so less clutter. I love Roku products and have been able to downgrade my cable service to basic only because there's so much available through Roku and its partners. And I am now using RCA digital antennas instead of cable boxes on two of my three TV's now because I objected to the cable company charging me every month for the two extra cable boxes. I love Roku!
We bought the Roku to watch Acorn TV on our new television. It worked fine the first night, didn't work at all the second night, then the third night it worked fine. So far, in our first month with Roku, this is the sum of our experience. We hope it will continue working fine and the only reason we got it is to watch Acorn. It looks like Roku also carries hundreds of other streaming channels but beyond the biggies like Netflix, Hulu and youtube but we are only interested in free other channels and haven't found any yet we're much interested in. Still, if the Roku stick works okay going into the future, it's great for providing access to all these streaming channels for a very affordable price.
Bout ours just before Christmas! It is an amazing device! Was easy to install and use! The capabilities are seemingly endless! Watching Netflix, Amazon and Hulu on the big screen is so much better!
