Absolutely awful. I couldn't find my remote on a business trip so thought I'd use the app. I got it working for 5 seconds and was like yayyy! It stopped working, then kept connecting and disconnecting. Suddenly a message pops up on the TV "Factory reset in 10 seconds". I couldn't stop it via the remote app that didn't work. Ran to the socket but it was too late. Now not only does the app not work but all the apps and logins/wifi are gone. Thanks Amazon.
