RE:Testing Now ...This article refers to saliva tests - not BLO s equipment. I have not seen any report/news item (even on BLOs' website) that indicates their equipment is undergoing testing by police forces anywhere. Perhaps they are keeping that under wraps until they get feedback from the field - hopefully positive feedback. The article mentioned that breathalyser test equipment is much cheaper than saliva tests because the only consumable is a plastic mouth piece - a positive for BLO.
