As of Jan. 17, this Apple AirTag four-pack is reduced to just $69.99, saving you $30.

Never used one before? The setup couldn’t be easier, simply attach it to your item of choice and track it in the Find My app. It even has a small built-in speaker, so you can trigger a sound from the Find My app on your Apple device, making it easier to find the AirTag if it’s nearby but out of sight, like under a cushion or in a bag.

Confused about the battery life? Well, according to Apple, all AirTags are designed to have a one-year battery life, with regular use. They use a standard CR2032 coin cell battery, which is user-replaceable. When the battery is running low, you’ll receive a notification on your iPhone, giving you plenty of time to replace it.

It even has an IP67 water resistance rating, meaning it can cope with a maximum depth of one meter for up to 30 minutes.
