Oh give me a break.
It's nonsense products like this, and people like you who give this HOBBY a bad name.
Sure, anyone could throw together any old piece of garbage, make ridiculous claims and statements for the effectiveness of their garbage (product), and try to sell it.
But it doesn't mean it's legitimate.
We the consumer also have the RIGHT to call them out on it, and to criticize their garbage (product); if one feels their claims and statements regarding their garbage (product) are deceptive, misleading, or downright inaccurate.
The consumer has the right to discuss, criticize or even spread the word to other consumers, if they feel there's a potential for other consumers to get duped or scammed on a particular product.
The manufactor has their rights, the consumers also have their rights.
They say there's a sucker born every minute. What they forgot to mention is, there's also a cynical, harsh, untrusting critic/evaluator born right along with that sucker.....every minute.
