I have been a Tile user but they never quite provided the reliability when something was more than just misplaced nearby (like keys between cushions on the sofa). The reviews for AirTags showing location are better but, unlike Tile, they have no means of attaching. (See photo) The silicone fobs provide total coverage for the AirTag and have a sturdy thick loop with a carabiner.
Time will tell how durable they are. Plus, no one will really know what's in the fob. The colors are not my favorites and you can mix and match the two pieces, but on key chain, it's not critical.
