The only drawback:
Peel off the protective film more color will definitely be released than in non Refills (own experience) and the drawer was slightly smeared (in all colors). However, this has no effect on the print quality.
Who can live with it, can access here.
Edit 06/23/2014:
Am now no longer so enthusiastic. I print very little, and then 65% level made the problem until later in ca bemerktbar:
The color and black print is not uniform. First images and graphics were blurred. Then paint by a large area created in any color and printed. The result was devastating. No consistent results, stripes and uneven color distribution.
The manufacturers / distributors written and described the problem. It has apologized and offered, for a 50% discount to purchase a new set - I did. However, here a few months later the same problem.
So only 2 star, after all, you can order print and in plain text, it falls not so on.
Meanwhile, I have again the original HP in it and no more problems ...
