I’m very pleased with my Boomerang - I haven’t tested the alarm function out of consideration for my neighbors but it’s got the battery life I found lacking in smaller trackers. I hope the next iteration has wireless charging or a more robust waterproof port cover.

From experience tracking down a different GPS module and stolen bike: If you tell the kids who answer the door your bike was lost and there’s a reward for whoever found it, things go more smoothly than getting the cops involved.
