## Description

Epson’s EcoTank replacement ink bottles offer thousands of vivid pages (1), while delivering genuine Epson quality. When it comes time to buy more ink, you save up to 80 percent on low-cost replacement ink bottles (2). Plus, these ink bottles feature exclusive autostop technology, with each color uniquely keyed for easy filling of each tank. Ideal for everyday printing, these ultra high-capacity inks mean you can go longer before replacing them for an unbeatable combination of value (3) and convenience. 1. Replacement ink bottle yields based on the ISO/IEC 24712 pattern with Epson’s methodology. Actual ink yields will vary considerably for reasons including images printed, print settings, temperature and humidity. Yields may be lower when printing infrequently or predominantly with one ink color. All ink colors are used for printing and printer maintenance, and all colors must be available for printing. For more information, visit our official site. 2. Savings comparison based on the purchase cost of replacement ink bottles and the cost of enough cartridges to achieve the total page yields of the bottles using the manufacturers’ online prices and yields for the highest-capacity cartridges for the best-selling, similarly featured consumer inkjet printers priced at $499 or less per NPD, July 2016. Actual savings will vary based on print tasks, print volumes and usage conditions. 3. Based on average monthly document print volumes of about 150 pages (ET-2700, ET-2750), 300 pages (ET-3700, ET-3750, ET-4750).

Review: My Printing Savior! Ultra-High Capacity, Incredible Quality, and Eco-Friendly Too! - Let me start by saying that the ultra-high capacity of this ink bottle is an absolute game-changer. With a whopping 127 mL capacity, I can print thousands of pages before needing to refill the tank. This means fewer trips to the store, less time wasted on cartridge replacements, and more money saved in the long run. The quality of the ink is equally impressive. The black text comes out razor-sharp with outstanding contrast, making it perfect for printing professional documents and reports. The ink also dries quickly and is resistant to smudging and fading, ensuring that my prints maintain their high-quality appearance over time. One of my favorite features of this ink bottle is its drip-free nozzle design. It makes refilling the ink tank a breeze, with no messy spills or wasted ink. The bottle itself is also compact and lightweight, making it easy to store and transport. As an environmentally conscious shopper, I'm pleased to note that the EPSON T502 EcoTank Ink is manufactured using eco-friendly processes and contains less plastic than traditional ink cartridges. This makes it a more sustainable choice, and I appreciate that I'm doing my part to reduce waste. Overall, I can't recommend the EPSON T502 EcoTank Ink Ultra-high Capacity Bottle Black (T502120-S) enough. With its impressive capacity, exceptional quality, ease of use, and sustainability, it's a no-brainer for anyone looking to streamline their printing experience.

A: Yes, it is VERY hard to find the amount of liquid in different bottles. They often do not state size. Some are 60ml, some 70ml, some 127ml and other sizes.  I still like the ink but its very hard to compare price and size.
