I am very impressed with this device. It exceeded all my expectations for such an obscure alternative TV interface. Unlike other similar devices, this supports Netflix and Sling, which I use enough to be worth keeping. Also, the device is advertised as Android 8, but it was upgraded to Android 9 once connected to Wi-Fi. It's fully functional from day one, with very good picture quality even on a non-4K signal. The user interface could be made a bit more intuitive. The volume control on the remote control is very convenient.
