I actually have one hopper preordered with three total invoices. I placed a couple orders for a leather sleeve and batteries for my Vaposhop hopper.Sorry for that. We do know how many backers there were initially and how long it took to get through them.
Based off that, I guess one hopper for every 3 invoices.
Edit: just a guess, probably on the low side.
Now, my Nov 2015 order has a #24,000+ invoice number.
My invoice from three weeks ago was in the 27,000 range. Does that mean only 3,000 purchases in 8 months? Perhaps my reverse bell curve theory should be modified as there doesn't seem to be much uptick in orders for the holiday 2015 season.
