I had almost a completely identical experience. Ordered, waited a month and nothing. Went to look at the seller's reviews .. and they were all 1/5 negative saying the product was never delivered. The A-Z guarantee got me my money back but I wasn't impressed the seller was allowed to continue doing this for so long. After I complained, the seller appeared to have all their items removed from Amazon. As an aside, you can generally trust the FBA items from 3rd party sellers.
