Pretty cool. Takes a bit of time to fine tune.
Initially, I didn't realize that I needed the app on my phone before setting up. I surmised that the QR code on the screen would bring me to the app store to get the app, as seems to be the normal way. Once I realized this, I downloaded the app and used the QR code to log into the unit. You have to hold the phone very far away from it, but it did work. It connects quickly and responds to the app better than most "smart" devices that you have to WiFi connect to initially to set them up. It also took a bit of clicking around to find where I could change a setting to show the flight number. It is on the bookcase behind my desk, and people ask about it on Video calls.
