Our take

Plugs into the OBD-II port in a couple of minutes, needs no subscription, and reports tilt, impact and movement to your phone. No monthly fee is a real advantage over every 4G tracker here. Two things to weigh against it. It runs on Amazon Sidewalk rather than a cellular connection, so coverage depends on other Ring and Echo devices being within range, which is fine in a suburb and unreliable in a rural car park. And at 3.8 across 757 ratings it is the lowest rated product anywhere in this catalogue, which is not a number to skip past.

Best for: Suburban driveways and car parks where Sidewalk coverage is dense
