I have no experience with the product nor do I know anyone who has, alas.

Although it may be a good product, the marketing as a "miracle"-anything does not bode well for it in my opinion. It gives me an idea of the kind of consumer they are targeting.

I have faith in God, and do believe in miracles... just not the consumer product kind :D .

For aquarium hardware, I'll take dignified advertising and hard science anyday over promises to cure Third World diseases, spare the need for water changes, grow hair, or water one's lawn.
