JeffOtto.com LTD's challenge to any of these so-called critics:
Put your money where your mouth is! $5,000 cash to be exact and we will do the same.
They provide a suitable shop at their chosen continental US location and we will provide a vehicle to be modified (a scientific before & after mileage check will be performed both before and after).
We will announce the date and location to give anyone that would like to witness the event adequate prior notice and it will be video taped.
They are also welcome to announce the event and have any of their experts present to test/examine the pre & post HAFC equipped vehicle.
If their experts can find anything bogus like a false tank, or whatever, they can announce that to the world as they see fit.
When they do discover the technology works exactly as we claim, they can than repent by issuing a public apology and remove any negative comments they have posted anywhere.
Obviously the winner will keep the losers $5,000!
