Thank you, Mr. What you saying is absolutely right. I know what to do. simply price$300 is not appealing.

My step is find other supplyer with less cost, same time try add-on to HHO generator,sell on street, build units by my self, sell on e-bay, build more, set-up web-site, set-up affiliate program, build list etc etc.

Simply, i love products but i have to compete with other on price then enhance marketing, web presence, loyalty of people.

Good price for great products, then marketing will be easy.
