522 Ink Refill Bottles Compatible with ET-2800 ET-4800 ET-2400 - High

In this review the 522 Ink Refill Bottles are assessed for small offices and home users who need a low-cost refill option for ET-series inkjet printers. The bottom line: these bottles deliver a high page yield and bold color at a fraction of brand-name cost, making them a strong choice for heavy black-and-color printing. The review finds the refill bottles especially useful when high page counts and simple refills matter most, with the one caveat being that a minority of users reported compatibility issues on certain printer firmware versions.

Key Features

• Broad printer compatibility: Works as replacement refill bottles for ET-2800, ET-4800, ET-2400, ET-2803, ET-2840, ET-4700, ET-4810 and ET-2720 models, simplifying stock for mixed fleets.
• High page yield: Each black and color 522 refill bottle is rated to print more than 8000 pages, reducing how often you need to top up ink for high-volume tasks.
• Upgraded ink formula: Uses a tested ink formula designed to produce clear text, bright colors and steady flow without frequent clogging.
• No-leak filling design: The automatic stop outlet closes when lifting the bottle after refilling to minimize spills and mess during the refill process.
• Included set and support: The pack contains multiple bottles in black, cyan, magenta and yellow and offers customer support with returns and technical help if problems arise.

Who It's For

These refill bottles are best for home offices, small businesses and students who perform a lot of document printing or produce color materials on ET-series Epson-compatible printers and want significantly lower running costs. The high page yield and easy-fill design make this set practical for users who refill regularly and want predictable results.

Users who require manufacturer-backed ink warranties or who are unwilling to troubleshoot occasional compatibility quirks should look elsewhere. Also, if precise color matching for professional photo printing is critical, a branded photo ink set is likely a better fit.
