What to know before buying
- The listing calls the set both 812XL and 812 replacement cartridges and gives a total yield of 5,500 pages. Confirm the cartridge version and printer compatibility for your exact model before ordering. The yield is a listing claim at 5% coverage, and the firmware-update advice may matter for cartridge recognition.

Less suited to

The supplied evidence contains aggregate ratings but no customer comments. The ratings are uniformly five-star in a small sample, which is encouraging but too limited to establish reliability, print quality, or cartridge recognition performance. For buyers, those practical outcomes remain worth considering alongside the listing's compatibility and firmware guidance.
