This product should not be ordered from Stemborg mail order because the product did not come in original packaging, was obviously refilled and were not recognized by the printer you. On housing were the remains of the yellow first fill and the transparent protective film was broken. The complaint does not proceed satisfactorily, because the seller claims no refilled cartridges for sale and is reportedly indicated in the product description that the "original" cartridge will NOT be sent in original packaging.
The purchase of Brother toner cartridges (Quality of the product, delivery, etc.) With other sellers has so far always entirely satisfactory.
