552 Pigment Ink Refill Ink Bottle for Epson 552 Ink Used for EcoTank Photo ET-8500, ET-8550 Printer (1 Photo Black, 1 Black, 1 Cyan, 1 Magenta, 1 Yellow, 1 Grey, 6-Pack)

NOT FULLY PIGMENT INK. ONLY BLACK IS. It has good reviews though. One person claims there printer had mixed this pigment ink and the oem dye ink. They may have sent only her/him a pigment ink. But I guarantee yours and mine are only black pigment and the rest dye.This is ok for me though because the actual pigment inks you find on search engines are about $60 for 100ml each.So for me price wise this is better.And I hear dye pictures are more vibrant and dont fade as fast as ones in lets say the 80sThis is marketed as a photo printer afterall.They wouldnt use dye it was super inferior even at a $650 price point.Unless your water coloring or want pigment id recommend go on the engine and look up an exclusive pigment ink especially if you want to put pigment in immediately.Also if you cant charge the printer… do a powercleaning it does the same thing. (For ppl who bought only the printer w/o ink)

Fast delivery, easy install, works great..

Works well the printer works without any problem

Since they're both labeled 552 I assumed this was a straight refill for the OEM ink for my ET-8550. It is not! It seems if you want to use this ink you need to start with a completely clean, empty tank. This is pigment-based ink and I guess the OEM ink is dye-based, which makes them incompatible, & if you try to mix them the result is an awful print with a bunch of ink that never dries sitting on it.I contacted ecodot/yoofun support through Amazon and they immediately gave me a refund, which is awesome. Still wish it was more clear that this is not a straight replacement and you need to empty out all your old OEM ink first before using this (and syringes are required to do this). It says it in the description but A) who reads those completely and B) I didn't know the OEM ink was dye-based so seeing that this was pigment-based didn't set off any alarms.

Can't beat this bargain, and i'm a photographer who develops pictures on the regular.

The ink worked as described, I followed the instructions and I have no issues with it. My machine is printing the same as it did with the original ink.

I'm so disappointed. I am a watercolorist who purchased a new Epson ET-8550 to print my line drawings and paint. After installing these inks (no other ink had been installed in this new printer), I printed the printer test pages. When all of the test pages were printed I went to the first page, well over an hour after printing, and ran a bead of clean water across the page with a clean watercolor brush. Everything except the BK black runs and bleeds. I also expected to be able to use this for my watercolor prints. The printer is set to print on Matte Paper, the paper I'm using is Bristol Vellum, 67 lb. To say I'm very unhappy is an understatement. Now I have a ruined printer

Great value. Just a good as the name brand
