Intelligent Bio Systems (INBS)

I am a newbie with investing and with evaluating the viability of companies. I started looking into INBS a few months ago and was surprised to find more investors weren't talking about this stock. Their product is already being implemented by companies all over the world, and they have just recently submitted their 510k so they can break into the American market. A non-invasive drug screening using fingerprint sweat that takes 10 minutes? With 95% accuracy?

I understand they will have to face competitors and that breaking into the US market will take time, but they have fully functional product that is about to be sold (pending approval) in an American drug screening market that estimated to be worth over 3 billion.

What am I missing?
