In heavyI for one am sticking by this company. The covid years have openned posibilities for RDT. It takes time to be taken seriously with the big pharma boys. This delivery system works and I say that it will be successful in the near future. $2.50 to $5.00 isn't out of the relm of posibilities. Try to find another product that has this kind of bright future. I'm in for the long run.
