522 Ink Refill Bottles 10-Pack for Ecotank Printers - Extended Yield

In this review the 10-pack of 522 ink refill bottles is evaluated for home offices and small businesses that use Ecotank and Supertank printers. The bottom line: it is a cost-conscious replacement that mirrors OEM refill behavior and extends replacement intervals, making it a practical choice for users who prioritize page yield and color performance over branded packaging. The pack is notable for its auto-stop no-spill design and 70 ml bottles that claim high page yield, so it suits anyone who prints regularly and needs a low-maintenance refill option.

Key Features

• Compatible Models: Works with a broad range of Ecotank and Supertank printers, so buyers can replace multiple series with one kit.
• Auto-Stop Design: The bottles feature an auto-stop mechanism that helps avoid spills and makes filling printer reservoirs easier and cleaner.
• High Yield Bottles: Each 70 ml bottle is rated to print up to 6000 pages at 5% coverage, extending the time between refills for typical office tasks.
• Dye Ink Formula: Uses high-quality dye ink formulated for smooth printing and vivid colors suitable for documents and photos.
• Support and Warranty: The brand offers 24-hour technical support and a defect return or replacement promise for customer reassurance.
• Not Sublimation Ink: Clearly labeled as standard dye refill ink, so it is appropriate for regular printing but not for heat-transfer sublimation processes.

Who It's For

This kit is best for small offices, home users, or students who own compatible Ecotank or Supertank printers and want a lower-cost refill option that behaves like the OEM bottles. It particularly benefits users who print frequently and need the convenience of large 70 ml bottles to reduce downtime and cartridge purchases.

It is not for people who require sublimation or specialty inks, or those demanding factory-branded packaging for warranty reasons. Users who experience inconsistent results with third-party inks should test a bottle first before committing to regular use.
