I never normally buy aftermarket printer ink. Mainly because of the bad experiences of the 90s. But for the price. I could not resist. The package arrived with no problems. The instructions included clear images as well as FAQs that addressed many "what if" situations such as error codes or poor print quality. But I've had no problems or error messages using my HP MFP Laserjet 31 printer. From my trained lay eye. I see no difference in print quality. And so far no stains, fading or other problems. Even though I only printed 31 pages of documents. Everything is fine. I plan to keep an eye on the printed pages. So yes, I recommend this mascara.
