I know the Fire requires a tablet to control it and many tablets will not work with it. Now they might have fixed that in the last 6 months. I have also worked with the Roku stick and the ChromeCast. ChromeCast was pretty buggy, it has gotten better. If you want to just stream Netflix, Hulu or other streaming services, the Roku is the best of the three. The difference being that the Fire and the Chromecast allow streaming from tablet, Smartphone or PC. In my case, I do everything with my PS3. I can stream any movies from my laptop to my PS3.
