I have tried several AirTag cases and keychains. They’re universally overpriced, and each one has flaws that make me feel vaguely dissatisfied with having purchased them. Here are some of the ones that I have tried, followed by a surprising discovery that ends up being nearly perfect.

First up is Apple’s Leather Loop. It is chic, pricey, and impracticable for any application where it could be subject to rough handling. But the quality is excellent, and it turns your AirTag into a fashion accessory.

Belkin’s version of the Leather Loop, which is made from plastic and paracord, is better priced but still expensive for what you get. If dangling your AirTag is your jam, though, it’s a less pretentious and more secure alternative.

Bellkin does better with their AirTag Secure Holder and Keychain, which was one of the first third-party cases on the market and, at the time, amusingly omitted the word AirTag in any of their labeling or marketing. (Go figure.) Its plastic construction is sturdy but doesn’t add any appreciable bulk, so that’s nice.

Elevation Lab’s TagVault is, by far, the most rugged and secure holder that I have tried. My issue with it is the Torx screws used on the enclosure, which makes changing batteries in the AirTag a pain in the butt. They’re a silly addition that only adds inconvenience, not security.

Pelican Protector AirTag Sticker is a holder that I’m very pleased with, but it’s very much for niche applications. If you want to hide an AirTag in your car, this is a fine choice.

Finally, we come to the most unexpected, inexpensive, and practical AirTag case that I have found. The Aldi Quarter Keychain. If you’re not hip to Aldi grocery stores — a cousin of Trader Joe’s — they rent you a shopping cart for 25¢. I guess it’s charming, and has given rise to various quarter-holder keychains so that shoppers can keep a coin close at hand. Aldi occasionally sells these keychains at the checkout counter for less than two bucks. And they’re nearly the perfect size for holding an AirTag. Just enlarge the opening for the coin slightly, using a sharp knife, and Bob’s your uncle. Seriously, if you don’t mind the Aldi aesthetic, you won’t find a less expensive and more useful AirTag keychain. (If you miss them at your local Aldi, you’ll find plenty of higher priced alternatives at the Amazon.)
