Hey Crager,
Thanks for the question. I know you might think I'm a bit biased about our product, but I'd be happy to answer any and all of this forum's questions about HHO/hydroxy generators.
There is a great deal of competition out there, and I encourage you to do your research. If you choose to build your own, please be very careful, as building it incorrectly can do damage to your vehicle or simply not work. If you would like to try it, we can provide you with some resources that will protect you from making such mistakes. You might want to consider buying a guide, which some of our partnering sites provide, or you might be able to get away with just watching a bunch of YouTube videos and learning from them.
In any case, whether you're interested in buying ours, or a competitor's or building your own, feel free to call me or e-mail with any questions you have. I would be happy to help you in any way I can.
