Bought 3 cards and got two free. The cards are perfect for use in my wallet and luggage. Installing on the Apple "Find My" app was easy and the fact that they are rechargeable is fantastic. Fortunately I haven't required to use the full capability yet but I did conduct a simple test hiding the card outside and asking my wife if she could locate it which she amazingly managed to do. The speaker on the card made in really easy once she was in the right vicinity as per the Find Me app. Wouldn't hesitate to recommend these, I has used apple airtags in the past for my keys but they were too bulky for my wallet so these were perfect and work just as well.
