The cartridges are packed in individual cartons and is once again sealed in foil. Prolonged storage should therefore be a problem. This I will also try even in terms of color cartridges because with me so far only the black Erstausstattungstoner is depleted.
When the cartridge is at least not refilled originals, although these were offered as Rebuild. The inscription "Epson" is missing and more insignificant differences on the housing can be recognized. I would guess a new replica. The toner opening is well secured with tape and plastic cap.
The small "lock lever" is a bit difficult to move than the original. The dimensions of the cartridge seem minimal departing. When inserting therefore a little more pressure than the original is required. This is to notice - but worth no disadvantage and no penalty.
The cartridge is easily detected and displayed in full.
When printing I had made with old toner some test prints. Even with a magnifying glass I can see no difference between the old and made with the replacement toner printing.
In this respect, a virtually flawless performance deserves the full 5 points.
If in terms of storage, durability or use the colored cartridge yield a different picture, I will add it here accordingly.
Addendum:
Meanwhile, I have used up a complete, compatible toner kit (almost).
Furthermore, I no disadvantages to the original are noticed.
The color cartridges are indistinguishable in terms of fit when installing from the original. A printed with original and compatible toners Test Photo likewise has no discernible differences.
I have already gained me another package as a reserve ...
