Fuzzy logic in esoteric products?

[Manuel Rodriguez]

Fuzzy logic is known as a fake science which doesn't provide useful
results but allows predatory publishers to become famous. Fuzzy experts
are calling the technique meta-mathematics or a new kind of thinking
but what they really want is to produce a nonsense paper and make a hoax
about the naive readership who aren't able to distinct between friend and
foo. There are a lot of noise papers available about fuzzy logic which
are explaining what the set theory is, or how to build robots. What all
these pamphlets have in common is that it's not science and that the
robot isn't working.

Additional to spreading out false information into the internet, some
advanced fuzzy experts had the glorious idea to sell complete product
based on fuzzy logic. usually that are esoteric products which are useless
and overpriced at the same time. For example a device to energize water,
a pendulum to swing out the healing process of a person or any other
humbug known from ancient fairs.

Has anyone more examples, how fuzzy logic is used in esoteric
products? Perhaps with an URL or with a youtube video which is showing
some non-working fake products in action.
