Platform flexibility sets this key tag apart: it can move between Apple Find My and Google Find Hub after a reset. A 120 dB alarm and molded ring hole aid everyday retrieval.
$38 typical
The spend goes into unusually complete everyday hardware: Bluetooth 6.0, a 90 m quoted range, 120 dB alarm, replaceable CR2032 and an integrated ring hole. Its useful cross-platform flexibility is genuine, but it must be assigned to one network at a time.
Low mass and a molded keyring aperture keep total carry bulk down.
A common user-replaceable battery avoids sealed-battery waste.
A small colored disc with a clean integrated hole—more practical and less accessory-dependent than AirTag. Six colors make identification easy without turning it into a novelty object.
Replace the CR2032 at roughly one year. The keyring is molded in rather than supplied as an accessory; IP55 is rain/dust protection, not an underwater rating.
