522 Ink Refill Bottles for ET-2800 ET-2400 ET-4800 - 5 Pack

In this review of the 522 ink refill bottles, the bottom line is practical: this 5 pack is aimed at home offices and small businesses using EcoTank-style printers that need an affordable, high-yield refill option. The kit includes two black bottles and one each of cyan, magenta and yellow, and it is best known for producing bold black text and reliable color output at a low cost per page. For anyone who wants simple refill bottles that deliver consistent results without cartridges or chips, this pack is worth considering.

Key Features

• Compatibility: Works with a broad set of EcoTank printers including ET-2800, ET-2400, ET-4800 and related models so you can buy with confidence about fit.
• Pack configuration: The 5 pack contains two black and three color bottles, which reduces the need to reorder black ink frequently for text-heavy printing.
• High yield: Two 140ml black bottles and 70ml color bottles deliver long print runs, making this economical for documents and multi-page jobs.
• No chips or cartridges: These bottles refill tanks directly, so there are no replacement cartridges to install and no chip communication required.
• Print quality: Customers report sharp text and vibrant colors, with black described as bold and suitable for business documents and proofs.

Who It's For

This refill pack is a sensible choice for home users, students and small offices running compatible EcoTank printers who want low running costs and high page yield. It suits anyone who does frequent printing of documents and occasional color pages and prefers simple bottle refills over buying cartridges.

Users who depend on guaranteed manufacturer warranty support or those needing sublimation ink should look elsewhere, since these bottles are thirdparty refills for standard document and photo printing and explicitly not sublimation ink.
