Here's the thing, we will know real quick whether or not he is full of S.
In the email he sent out in October he talked about an issue with the curing process, but more than that he said this
" I have a lot of Jboxs going out in the next week or so, if yours is one of them you will be getting tracking info email."
Now I'm guessing those never got sent. Presumably they were finished or very near finished. He should be sending some out in very quick order, if he is being truthful. If I don't see someone post buy, I'll say the 15th, that they got shipping notification or got their JBox, I'm going to take it on its face as he was just buying time.
This is all assuming that he didn't set out to rip people off and was working all along, then just got overwhelmed and at the worst possible time had the unthinkable happen, which caused him to go into a shell for a month or so, leaving many of the devices in a state of just begun, half done, near done, and so on.
