I see it like this: the VHW is essentially a remake of Hot Glass, but better. Both are based on commercial ceramic soldering irons. Now I am sure that if you check Amazon Reviews for commercial soldering irons, you will find a few quitting, a few perhaps smoking, and a few etc, etc,. Thus with the current design in the VHW, these same complaints are bound to happen.
So I do think Vriptech should be selling these.
But on the other hand, I also think they should be redesigned. I mean from, say, an investor's point of view. I would like to see the handle and heater hand-engineered first of all, because I have a feeling these are simply special ordered from a commercial soldering iron maker (see the striking similarity in the handles of Hot Glass and the VHW). Second, I would want the handle to be entirely different, so that the whole thing takes on a miniature ray-gun appearance. It could probably be patented on this aspect alone. And thirdly, one should be able to turn a dial (even if a somewhat tough dial), and the ceramic heater either retracts into the glass, or else the glass extends forward leaving the ceramic heater behind a bit.
