Due to various articles in technical papers on spare cartridges in general, I was very worried that these replicas may harm my printer. , Hence my great relief, when I had the first replacement cartridge inserted about 2 months ago (cyan), and this fit the bill perfectly right away and was easily recognized. For me there is no discernible difference in the printouts. , I, I then changed two more cartridges (magenta and yellow) and even now still seems everything perfectly fit. So far, my enthusiasm for this product is therefore large. I hope that the big surprise is not coming and therefore forgive this product with conviction the 5 star.
+++ No difference in quality to the original cartridges lockable +++ Excellent value for money - The original cartridge is indeed much more expensive. +++ Cartridges fit, are instantly recognized - and made no negative experiences so far (a few months use).
Negatives: So far found nothing !!
Supplement for more than 4 months: I am really happy that I bought this product. I notice no qualitative difference in the print and are therefore using this product in the future.
