It is great and as described. The concept itself may not work for you.
I was hoping for some way to use my AirTag to keep track of my wallet, and this seemed to be the correct answer.  However, it is really too thick for my wallet, but this is not the product's fault.  It is just how thick it needs to be to protect the airtag.  The product is exactly as described, and there are no quality issues with it, you just have to determine whether sometihng that thick will work in your wallet.
