I have invested in certain medical industry stocks over last many years, and this one reminds me of SPNC back in 1996 when I lived in Colorado and invested when they went OTC from private and purchased around 15 cents/share then. That stock uplisted and went to around $27.00/share eventually and trades today still on big boards...
Same could easily happen here because they are in a niche" of their own with NO competition at all and spent years developing everything "correctly" to where we are at today...
