Who Should Buy An Android Set-Top Box?
Android TV is my smart TV operating system of choice. I’ve used Roku, Amazon Fire TV, and various alternative smart TV operating systems, and I keep coming back to the Android option. If you like customization, flexibility, and integration with other Google apps and services, it comes highly recommended.
Given the wide variety of price points, you could easily install a premium Android TV set-top box on your main television and then use cheaper Android TV dongles on other TVs around your home, thus getting a consistent user experience in your whole house for a reasonable price.
I have it now and it’s a very good box no problems with it
