This is excellent news indeed, and i am guessing it is linked as follows but I could be wrong:
We know the following:
1. The QS-B220 underwent a trial at a shipping company.
2. During that trial it successfully detected drugs twice in packages, that when inspected by US Customs, confirmed the presence of drugs.
3. Today there is a PR saying there was a sale of B220's to "a major shipper".
Maybe those 3 events aren't connected, but I am guessing they are - but I could be wrong. In any event, it does show the QS-B220 works, and is starting to generate sales, no one can dispute that.
