So far there has been no reason to suspect otherwise. We have had many of communications with various staff members from their sales department and they have done nothing to make me suspect any worse than when I had ordered from BFL, yet here I am looking at my BFL units hashing away.
In addition.. As I've said before, if you go back a page or two.. There is a blockchain.info link with a wallet address. All money that has been received for orders are saved. No money will be lost, and if for some reason AM doesn't deliver, everyone will receive a refund.
