B&H cannot add any product by any manufacturer to an M1 or M2 Mac. They have to custom order it from Apple, just like you just did.

As for the SD and CF cards, I don't know of any tool to test their integrity. Your device will report any errors when writing to or reading from one of the cards, at which point you should immediately consign the card to the shredder.
