Printer performance and durability are great. Value and color if good it’s easy to use and fit right.

Gone are the days of buying a cheap printer only to go bankrupt on toner. This Epson eco-tank lasts a LONG time. I'm getting the lowest cost-per-page I've ever had with my Epson STM3000 and companion ink, and the pages look good.

So glad that amazon carried this product. Works good!

So happy our printer takes this ink. It lasts us about 6 months …. At least 3 times longer than the ink cartridges we used to buy for our former printer. Very happy with this product.

I've had this printer for two years and the ink has never gotten gunky or sticky, always prints beautifully, and lasts forever. I went through 3 printers during COVID where the ink dried up and it wouldn't print and the whole machine got wonky. This has been an amazing printer and the ink couldn't be easier to replace.

Had to use top from old bottle to get the ink in printer. The new bottle top was not compatible to my printer… be careful.

This the design of the bottle incompasses all of the thought that needs to go into applying it. Most important is compatibility. High quality ink is the best to use. Cheap will damage your equipment. I put this in and a year later I buy some more.

A 532 bottle came with my printer. At year three, I bought this ink thinking I'd need it soon but didn't. Thankfully, it arrived with a 2027 best-by date. It's 2024, and I'm ready for the first refill after printing 1988 black and white pages on the original bottle. I'm mostly printing PDFs and I get very nice, saturated text on 24-pound Epson paper.

Great product easy to refill with no mess and lasts longer then the cartridge option.

It's my first time buying a refill since 3 years after owning the printer and finishing the bottle it came with. Great stuff (ET-M2170)

Godd product. Good service.

I will never look back to old fashioned printing. I only replace my ink on my Epson Eco Tank MT2170 every 2 years. I bought this ink because sometimes you might not find it in stock I have noticed. Be aware you should only buy one such ink bottle at a time. The ink has an expiry date. If you buy two bottles, you will be running into the ink bottle expiry date for the second bottle given its 2 year capacity.

Ran out of ink and needed right away. Local store did not have any available. Ordered and received it the next day for a few bucks cheaper.
