Ok I've bought a few aftermarket cartridges in my time but this product far exceeded my expectations.1. The packaging is impeccable. The cartridges came in a small, sturdy, well-designed box, each cartridge was individually wrapped and securely fastened.2. Surprisingly, I receive an email from the owner explaining the product's warranty and offering a link if I need help. Cartridges have 1 year outrageous warranty.3. Introduce. I received a small booklet with instructions on how to set what not to touch and how to reset errors.4. Last but not least is the performance. I put in the cyan cartridge, it registered as full and prints like a dream. I wish this company every success and hope that it will hold its own in a really tough market. It was a real pleasure doing business with you!
