Have bought with the set for my Epson WF-3540 and have been so calculated that it is no good, or is not recognized by the printer. But everything works well. Interesting for others who want to buy the large set, the cartridges are all individually wrapped, so that you only contact with the medium that you need and only opens. The others remain in the closet are on stock. The cartridges are even tanks, since the cartridges that I was from HP always knew the nozzle head to the replacement cartridge off. If you are then stored for longer you could throw them away, because the nozzle head was glued. The Epson here it is only the ink tanks with one changes, so nothing can stick .... Thanks also to the developers from Epson
+ Only tanks, nozzle head in the printer, so long storage times + Real low + Are easily recognized by the printer
- Shipping took 2-3 weeks, but if you know it's not bad
