I've had it over a year. I don't tap to pay with the phone (I have a classic wallet, cash, cards. I have lightning wallets on the device when I'm somewhere that is accepted).

I occasionally use a Garmin watch for running and it pairs perfectly well with Garmin's companion app. If I'm feeling super paranoid about the companion app, I could throw it in a totally isolated "user profile" on GrapheneOS (but I haven't done that yet).
