Didn't even have a cord and plug hooked to it. Think that was by accident? If that thing would heat water, believe me they would have been thrilled to fire it up in front of us. I could put the cord and plug on in a few minutes tops. But that wasn't by accident, that there wasn't any live demonstration for us and no efficiency numbers, STILL! That is a duuuuuh moment, send us all home happier with the numbers and a demonstration if they could, but they can't, jmo. More stalling...
