I did not overlook the devaluation of the product in the title, which can only be a result: "Snake Oil". This is why I said: "No measurements AND no experience." But he came to a conclusion: It's snake-oil. Unprofessional.
No honest, reasonable assessment of this "product" and its marketing can conclude that the manufacturer appears to be on the level. Expecting journalists to wade through literally infinite bullshit from people not acting in good faith before reaching a conclusion is absurd. Your perverted idea of what journalism should be is far more harmful than any journalistic laziness that may be on display here.
