Biggest value I got from my Flipper was when a security company was installing a security alarm in my business local, and made a claim that their tags were "unhackable" and "unclonable".
~20 seconds and one cloning later, the installer said something like "Wow, guess we need to update the employee handbook" and I no longer felt comfortable with the installation so asked them to leave after that.
I also once forgot the garage opener to the public garage I usually use, but had the signal saved on my Flipper, so that saved me like 5 minutes of not having to park, go home, go to the car and then park inside the garage.
Otherwise, it's mostly just for fun.
