"Engineers may make additional adjustments to the BCU based on this early testing of the unit..."
Correct. Early Testing. Like Early Testing in 2014, 2015, 2016, 2017, 2018 & 2019.
When does mid/late stage internal testing begin?
There after, when does 3rd Party testing/evaluation begin?
5 years from now would be a good guesstimate for 3rd Party testing based on a track record of news releases and refreshed gadgets viewed in pictures.
At least the Nanose came with a video when it got pimped and hussled to shareholders by the same President (Kal) and the Science Guy (Raj) of Cannabix & Breathtec.
The last device we saw on public display @ Cannabix was the Beta 1.0 That gadget was simply a prop without any internal workings. It could have cost us a lawsuit based on the BuzzFeed article there after.
