work great!

Great price for OEM ink and fast delivery.

I bought this ink to refill an off brand CISS for my Epson WF-3640 printer. The pigment inks seem to clog up the new Precision Core print heads. I have been through 3 of these printers in the last 2 years. We do a lot of printing in my business. Since I switched to original Epson dye based ink about 3 months ago, we have had no problem what-so-ever with print head clogging. I would definitely recommend this ink in any CISS.

I use this for everyday printing and they do great

Works great—

Value for the money, ease of use, lasts a long time...

Best used by date was 7 months ago - not happy but will use - hope it works. Fresh would be much better as I only need to re ink every 3 or 4 years.

Second purchase of this product.

Convenient

It took 24 hours for the ink to start printing correctly, but the quality was just as expected by the next day.
