Surely ordering the beta would show straight away that the product was entirely non-functional (ie fake)?
Did I miss something that you're relying on to form this opinion?

The biggest giveaway in that particular campaign though is something that most ordinary people won't pick up on: gluten. You tell someone that a spectrometer can detect sugar, they'll nod, you tell someone that it can detect gluten and they'll still nod, but people who know better will have their ears perk up. Because gluten is just a protein, and proteins are a nightmare when it comes to spectroscopy. Spectroscopy picks up the different bonds that are in a molecule. A simple molecule with only a few, very different bonds is easy to distinguish. But proteins are polymers made up of tens of thousands to millions of amino-acids, which blur together in spectroscopy. To distinguish different proteins from one another with any kind of spectroscopy (whether Raman, IR, or even NMR) requires high end equipment which can give you very high resolution spectra. A low cost, consumer grade spectrometer is going to have very low resolution and be even more difficult to do. If they could pull it off it would be a tremendous breakthrough. The idea that they've made such a huge leap without seeking traditional investors to go after the industrial market, without any substantive research backing is, frankly, not robust against the much more realistic probability that they are pulling some sort of scam that involves a device that maybe has some capability or other but is nothing like what they say it is.
