As stated, I actually tried Cilit Bang. And whilst he might have convinced you that he believed in the product, as a user of it I can tell you with all sincerity and without bias that it was completely shit at it's core function, and if I actually cared enough, I would have had it banned as misrepresentation as it is not suited to the purpose for which it was old for. I didn't even finish the bottle, I just chucked it away. Useless stuff that sells entirely on marketting.
Saying that somebody in marketting was a good person is like claiming there is such a thing as an uncorrupted politician.
