Ever notice the vendors of these things never provide any empirical data to show that these things work. That's a huge BS flag right there. I mean surely while they were doing the research and development they had to keep a record of the numbers and data right? Otherwise how would they know it works? All they have to backup their claims is anecdotal reports. The demonstrations I've seen for these things are laughable. A video of some guy filling up his car, driving from point A to point B, filling up the tank again and literally using the numbers from the gas pump to make comparisons. I mean these guys invent a supposedly revolutionary, ingenious product and these are the best, most precise scientific methods that they can come up with to prove their product? lol.
