I received one box yesterday and one today. The first 3 were packed well and are in good condition. They hash just fine. I haven't opened the second box but I anticipate the same.
Good price for these even if they are inefficient. Good seller and I would buy from graymatter again.
I used the BFL BFGMiner variant here:

Was seriously thinking about order a pack of these, but I'm kinda glad I didn't yet as the profitability took a huge nose dive down to like 15 cents a day lol.
