ok. I watched the video, it mentioned that the hydrogen purity of 99.996%. If you possessed certain science knowledge you will see how BS this is... H2 is extremely flammable at such a purity, it reacts with O2 and create massive fire if not explosion.

and the youtube ads doesn't even mention the source of H2? from electrolysis? from cylinder?

and again, it does not even mentioned if inhale in fully H2 or mixture of H2 + O2? again, our body can't inhale air with less than 19.5% oxygen in it. fully inhale H2 or if the H2 and O2 is not well manage it can make someone faint immediately or even die from it?

Ok, I think i raised enough questions on this thing. Please consider carefully once again before consume it.
