I received mine today as well. I'm quite happy with them, understanding that this is the first batch. It would be nice if the private key didn't cause a bump in the lamination (at least, it appears to be laminated), but it's not a deal breaker.

Jim, I'm definitely interested in the results of your security test.

llama, if you read this... A smartphone app to go with bitbills would be awesome. There are only two necessary functions, I think.

1) verify the balance of a scanned address
2) send a transaction using a scanned private key
