AirTag and Faraday protector
There is a fundamental problem with the AirTag. I keep my key fob, which is attached to my AirTag, in a Faraday box. The Faraday box blocks the key fob signal from being stolen and used to steal my car. If you put the key fob and AirTag in a Faraday box for longer than 8-24 hours, it gives off a bunch of noises the next time you move it. I understand why you decided this, but it has a significant downside.
