I wanted to try these cartridges despite the streaky reactions, because I at the low price, the risk also appeared low. The cartridges come in good packaging and with a detailed installation instructions, which should be noted. To this end, before a big compliment. Unfortunately my HP8700 did not print with the cartridges and I got the dreaded in HP circles "error is detected" message. After some back and hermailen with the service I was offered to send me a completely new set of cartridges! Unfortunately, so that the error did not go away. Meanwhile, I also had a set of original cartridges and therefore it does not work at first. Always the blue cartridge has displayed an error. Just before I thought the printer is out we went but again. At the moment the cartridges therefore are currently at my home in the hope that they do not dry out. If the originals are then empty, I can once again check the functionality. One star deduction, because it just did not go first and I was pretty scared, but at least 3 stars for the great service! Another for "The benefit of the doubt", maybe then yes funktioneren later all cartridges except blue, then still ne quite a savings. To all the awarded only one star: did you also turned to the service? I would recommend this only!
