Interesting that you bring up the patent.
Before I order the unit, I did a deep dive on other units in the market. I also questioned the company about the history with their product.
Turns out the machines are now in 52-countries. The company has been selling water units for over 13-years. The machines use to have a failure rate of 30%, before the current improvements.
I learned that the patented Ozone was the "game changer". This was the feature that sold the DOD and why they landed their contracts.
IMO, the DOD will open a LOT of doors going forward.
Yes, there is a whole lot more to what is going on behind the curtain here.
