Crooks. They write this high pressure sales routine, complete with: oh, and there is only 100 left, will be sold out in the next 10 minutes, sale price only good for the next 8 minutes. "Cut your fuel consumption in half with Syngas". Seriously, and the car companies haven't thought of this? They can't design this in? Add doesn't give company name, address or contact info. They lie and tout 4.7 stars with 8,200+ reviews. Not getting my $$$.
