Only Ugh, then hui ... (corrected review)

With the purchase of the new printer, I also bought replacement cartridges at the same time. Meanwhile, 12 of these cartridges (2 x 6 pieces) 9 been used, although I have only exchanged one set of cartridges. How come? The CP 550 XL (black), the CC 551 XL (gray) and the CC 551 (blue) each were not recognized by the printer, which is why I had to use the second set, which then, however, worked perfectly. (That's why more than 1 star)

Conclusion: With these failures I could have, like the more expensive kit buy cartridges. This sentence is cartridges, as its one or other reviewer has noted, could not be recommended also, in my view!

Addendum: It was sent as a replacement, of which so far have all been recognized, which is why I have to correct my opinion, a complete set (12 cartridges). I forgive provisionally 4 stars for cartridges ... a 5. I give when they all work!
