Work well with Epson printer and last a long time
Style: Ink
These ink cartridges work well. I have an epson workforce pro WF-4730 printer and these ink cartridges work perfect in it and save me a lot of money. I suggest you shake the cartridge first before installing them then perform a nozzle cleaning and check afterwards. I've never had one fail. The colors are accurate and the ink dries quickly. I especially like the large capacity of the cartridges. I like to have a full set on hand so I don't run out, but they last a long time.

EPSON OEM ink....
Style: Ink
Good overpriced Epson ink. Tried aftermarket ink, worked FINE until Epson "update".....then got notice "invalid cartridge" and the printer would not operate. Bought OEM ink and it's happy again. I'm NOT.
