522 Ink Refill Bottles for ET-2800 ET-4800 ET-2720 - Value 10 Pack

In this review the 522 ink refill bottles are presented as a practical refill solution for owners of compatible EcoTank-style printers. The 10 pack provides a straightforward way to replenish black and color tanks without chips or cartridges, and the biggest reason to buy is the combination of high compatibility and large bottle sizes that customers repeatedly praised for long life and reliable color output. For anyone who refills frequently, these bottles offer clear value and predictable performance.

Key Features

• High compatibility: Works with a long list of EcoTank and ET-series printers so users can keep a single spare kit for multiple models.
• Mixed 10-pack: Includes four black and six color bottles which reduces the need to buy separate colors and keeps a steady supply for both text and photo jobs.
• No chips or cartridges: Bottles refill directly into EcoTank reservoirs so installation is simple and avoids extra waste.
• Large yield: Generous bottle volumes are designed to deliver thousands of pages per bottle at normal coverage, minimizing refill frequency.
• Consistent output: The ink produces sharp text and vibrant images that customers reported as indistinguishable from expected printer output.

Who It's For

The 522 ink refill bottles suit home offices, small businesses, and students who use compatible EP/ET-series printers and want to cut printing cost by refilling EcoTank reservoirs. It is especially good for mixed use where both high-volume black text and occasional color documents or photos are needed because the pack balances black and color bottles.

Those who should look elsewhere include buyers who require OEM-branded cartridges with warranty-backed chips or users who need sublimation ink for fabric printing, since these bottles are not sublimation ink and do not include electronic chips.

Pros & Cons

• Refilling is simple and tidy with no chips or cartridges to manage, and customers reported few spill issues.
