EPSON Original Refill Ink Set (T6641 T6642 T6643 T6644) for L100 L110 L120 L200 L210 L300 L350 L355 L550 L555

They work fine with my eco-tank printer. I believe they ARE OEM.

I absolutely LOVE the Epson eco-tank printers and their printer ink. I’m wary of the off-brands and don’t feel comfortable trying them and mixing with the original name brand and chance ruining my printer but the cost is EXTREMELY reasonable for how long this lasts. “Saving” a few dollars by going off-brand is a risk I’d rather not take.Colorfast and vivid. Epson is superior to Canon (which I used forever and wasted hundreds of dollars on) and HP. Hands down! Although if you’re not careful with refilling, and the ink gets on your hands, you’ll be stuck with it for a few days despite scrubbing - that’s how good it is! (LOL)Stick with the name brand here - you won’t go wrong! As I said, I absolutely LOVE my eco-tank. In owning mine for 4 years I’ve only had to refill it 2 1/2 times - the 1/2 because I thought the ink might be low at 1/2 tank - and it wasn’t. That ink lasts a VERY LONG TIME. I also use the printer daily on both plain and photo paper printing up to 30 pages some days in color and black & white. Worth its weight in gold.

Moved from the HP Cartridge Hustle when they locked out refilling cartridges years ago and never looked back. Moved to EPSON tank printing and now on my second printer after several years (Just wore it out but got my money's worth out of it). Got a new EPSON tank Printer same model newer version works great with the ink. Saving $$$ over HP Ink.

Epsom ink products are great

These appear to be real Epson inks. I topped off the reservoirs and printed several color photos which turned out good. After you fill the reservoirs, don’t forget to go to the printer’s maintenance menu and do a test print / clean print head as necessary. Also do a “reset inks levels” in the printer’s maintenance menu or the printer will keep complaining about low ink.

When using this product I would wear gloves and be sure to put an old towel under the ink wells of the printer. It can get messy to fill the tanks as it is hard to see the fill lines on the tank and over flow. The ink will not come off of furniture or hands easily, so be sure to protect. IF you do not use all of the ink. It will leak if not stored upright. As an added precaution I just used a little piece of foil under the lid just like the seal that comes on it. Then put the caps back on. Ink color seems OK. Paging the ink bottles were in vacuum sealed before placing in the box. Which is a good think because the boxes were crushed since it was just sent in a large envelope instead of a box.

Love my epson printer, using this ink saves quite alot of money. Good quality.

The Eco tanks are good at saving money on ink. So it's easy to forget to refill the tanks. It can take months to empty a tank. There are cheaper brands out there but I know how these print and don't want to regret some money saving choice later. Buy the other stuff and you may regret your choice for a long while, and get reminded of it with every use.
