I have a Chromecast & was curious about the Roku, so I decided to try it out. It's a world of difference. Basically like having a smart TV without the cost. I love the remote as well. It just makes navigating to different apps so much easier than working from your phone. Also, you don't have to have the app on your phone to get it on the Roku.
The entire setup experience was simple and very straight forward with included documentation. Channel selections are great and picture quality is equally good.
I am extremely happy with the Streaming Stick. It has everything anyone would ever need at an amazing price. Another bonus is that it streams fast and the picture quality is amazing.
For the price it's hard to be overly critical of the Roku Stick. I have a Roku 3 and love it, so i decided to add a Roku Stick to an additional tv. Set up is easy, the interface is works well, my only issue is that it is much slower than my Roku 3. Apps load slower, it takes longer to load videos than my 3 (which is approximately the same distance from my router), it's a little less responsive to the remote than my 3. None of these issues would keep from buying it, but i should have sent it back and ordered another 3.
