My grandparents, whose little farm was next door to ours so my sisters and I grew up effectively with two houses and two very different sets of parents, were lovely people.

Apple made AirTag randomly chirp when bumped or moved when out of bluetooth range of your iPhone. That's great, but if your bike is stolen - the very last thing you would want is for the thief to hear the AirTag and throw it away. That's why we designed The AirTag Silencer - a patented precision tool that helps you disable AirTag's speaker in seconds - all you need is a hammer. Easy to Use - Remove AirTag's battery & set on the baseplate, place silencer, and hit piercer flush with a hammer. Disconnects the coil that powers AirTag's speaker.  Works on multiple AirTags. Invaluable for expensive bikes, camera bags, purses, electronics, backpacks, etc... Anything you wouldn't want a thief tipped off by AirTag's chirp. And its great for pets too - no chirping on their collar in the middle of the night. Also available on Amazon.
