Yes the product does work, however people were being decieved by the marketers that were exagerating on how much one can save and were also pushing that its easy to do - its far from easy. Only a fraction of the buyers manage to do anything since you need to have some background - this is the main reason why google banned it. (Apart from people complaining)
You don't have to try something to understand that it works. I've seen facts on the news and all over the Internet, that running a car on water IS possible. Even that I haven't tried doing it, it doesn't mean that it's impossible. if you don't satisfy you can asked for refund..no more pain Have you searched for other sites? Did you see it? may be you should see this.... it's has review many sites like water4gas or runyourcaronwater etc. carwaterguide.blogspot.com
