my mom gave me her unused Roku stick because her TV already contains these features. I don't know everything about it, but it's easy enough to find what you want to watch!
We bought a Roku for one of our tvs and liked it so much we bought a second one when we bought a new TV. However, I prefer the old remote better than the new remote. The "OK" button and the arrow buttons get stuck at times with the new remote, but the "OK" button is a separate on the old remote.
The Roku streaming stick is a great product. It's very easy to set up and use, and it boasts an outstanding variety of apps. On top of that, it's very portable, and easy to take from one room to another. This was the main reason I chose the streaming stick over the other Roku devices. However, I do have a gripe with it, however. Unlike other Roku products, you can only use the remote provided with the streaming stick, and not other universal IR remotes. Had I known this, I might have purchased a different Roku product, as I'm not a fan of the remote. It feels cheap, and I had to replace it within a month, as it simply stopped working. However, a laptop or smartphone can be used as an alternative. All that said, the streaming stick itself is great, but make sure you have an alternative to the remote before buying.
