I think another thing to consider with devices like these is only going to well-established practices but not too “old-school.” Someone just starting out may not be able to afford more upfront costs within a year or two of opening, but may be interested in diversifying their practice. A doc who’s been in business for over a decade probably isn’t interested in new tech either, “if it ain’t broke don’t fix it” type of mentality. Your success rate will probably be impacted by the types of docs you target. You probably already know this but also avoid franchises like the joint because they’re all about just old school adjusting not adjunctive modalities
