I represent a medical business who has been ordering high quantity cartridges from Atlantic Inkjet for several years. We had problems with the remanufactured cartridges working in our printers, went to original cartridges but by then our printers would not work. I tried to make a return or get credit for several unused, unopened cartridges but the company refused any credit or refund at all. They could not care less about keeping me as a customer and I urge you to not order ANYTHING from them. Janet R.
