Sorry to day that, but the promises from envion were wrong from the start one, the math was wrong. It was calculated as the units were produced instantly - which is impossible. The more money was given to them the lower (!!) the ROI in the first year would've been, because all that money has to be converted into units first. And they were so slow in the process, that they were unable to proof any running units after months have passed.

The failure of envion was obvious in january '18 - at least IMO. Show me otherwise.
