I've used item finders for years, especially for locating keys in my car or for keeping track in my purse and luggage. Previously, I used a brand with replaceable batteries, but they've switched to built-in batteries with a limited lifespan. As an Apple user, I appreciate these finders for their self-replaceable batteries and easy setup with the Find My App. Just press the button on the finder, add it in the app, name it, and you're good to go.
