If I didn't have the Flipper or some other SDR device I'd probably have assumed it was bad and left it at the recycling station. If I'd lose the original remote I can use the recordings on the Flipper to either control the sockets or create a new remote.
I've also looked into how the key fob to my car works and investigated tens of RFID and NFC cards, some of which I could probably have talked to with my phone but I like the format of the Flipper and it has very few distractions except Snake.
When traveling I sometimes bring it up just to check out what radio stuff I can find and think about what devices might be sending.
