As someone who works in high tech serviceI can tell you what they have set up is very profitable...once the cost price of the torch has been recouped by the company through reoccuring payments which probably wont take long considering they are building them themselves it becomes a snowball of continuous profit.... these things are plug and play so even if they have to be serviced every couple years or so they just pull them send them back to PYR they replace the worn components ( not the whole torch) and put them back in service for a minimal cost...as a service technician that deals directly with this sort of thing i can tell you reoccuring revenu stream on this will be huge money. Good on them.
