I linked this Find My device with my Apple phone pretty quickly. Then, I could easily attach it to my bike using the magnetic holder. It takes some effort to push the tag, which comes separately from the magnetic holder, into the holder, but it goes in quickly with a bit of pulling. Overall, this is an excellent option for those who like these tags and put them everywhere, from keychains to things with wristbands. In this case, you can easily attach it to anything metal, or it includes something that you can stick on, something that isn’t metallic, and stick to it. Easily replaceable CR 2032 battery (included).
