I didn't know that they had all the formulas. I thought they had the equipment and somebody had reverse engineered the film.
It's good to know that they have the information.
As I said, I'm not ready to buy yet but, IF I did buy today, it would be because I am curious to see how the product has progressed so far and it would be because I want to support the project.
I wouldn't expect it to be perfect but, for the money I would pay, I expect them to try their damnedest to make it as perfect as possible.
