Most Apple products are pretty expensive, but some of the most affordable (and useful) ones are AirTags. The Bluetooth trackers are priced pretty reasonably even when not on sale, but they can be a steal if you can

AirTags have an IP67 rating for water and dust resistance and their replaceable batteries should last for about a year. They can also support Precision Finding, which gives more exact directions to a lost item, when paired with most models after the iPhone 11. Up to five people can share an AirTag's location, which is helpful for families or large travel groups.
