The thing with inventions is that it has to have gone through scientific tests by peers and experts alike. These things are recorded, published in some scientific journal, etc etc. All chemical and physical reactions are noted. It seems this product hasn't gone through that and just went straight to marketing the damn thing.
Sure at first it does seem to work to some. But if you look at the numbers (where are they by the way?) something could be amiss.
And scientific tests don't mean one or two at the DOST. No offense, but our national science & technology program isn't one to be proud of (lack of budget I suppose).
Which is why the engineers here are looking for those. Only based on scientific evidence could they conclude that the thing works.
Personally, I'm waiting for expert opinion. Otherwise, I think the product is crap.
