Losing your luggage might not be the end of the world, but it’s definitely the worst part of a trip. That’s where something like the SmartLock comes in, and a four-pack of these TSA-approved travel locks is going for $79.99 on StackSocial right now, which is the same price Amazon charges for a three-pack. It’s designed for Apple users, integrating directly with the Find My app, so you can track your bags on a map, ping them with sound if they’re nearby, or get alerts if you’ve walked off and left them behind.
Each lock uses a simple three-digit combination and is TSA-approved, meaning airport security can access it without cutting it open. The build feels solid, with a durable alloy shell and thick cable loop tough enough for typical travel abuse. It’s also refreshingly low-maintenance, with no constant charging needed. The built-in battery lasts about three months and is replaceable, so you’re not tossing the whole thing when it dies. You don’t need to install a separate app to manage the tracking either, if you’ve used Apple’s Find My for AirTags or devices, the setup will feel familiar and straightforward. You also get solid tracking features like Lost Mode and sound alerts.
That said, this is Apple-only. If you use Android, the Find My functionality won’t work, so you're better off with a traditional smart tracker or lock. If you're traveling with multiple bags or coordinating group travel, getting four in one pack makes the price easier to swallow. For frequent flyers or anyone with a track record of forgetting their carry-on at Gate 17, this is one of those travel add-ons that might actually be worth it.
