I've looked into several similar products over the last few years,
invariably none of them were any more effective at insulating than a
clay-based paint. I have no experience with this particular product,
but based on similar ones I've seen, I'd lean towards snake oil. I
hope I'm wrong about one of these products eventually though, as
paint-on insulation would be very beneficial!

The closest I've seen to a thin insulation that have proven results
are aerogel-based products:
