No problems, print quality as the original cartridge

Goods arrived neatly packed and with short delivery times.
Each cartridge is individually wrapped. The insertion of the cartridge caused no problems. Although the printer (HP Officejet Pro 8600) showed the message that it is not genuine cartridges, but after I had pressed "OK", there was no funny business. I changed the previous two rounds.

We flew in to use a no-name cartridge, because in other products often poor reviews to phrases such as "print head is now broken," "could throw out the whole printer" ... I'm not sure if these negative reviews are really genuine.
I am glad to have anyway saved a lot of money. From the print quality I can not tell the difference to original cartridges.
I am very pleased!

UPDATE 22/06/2015:
Our printer did not work correctly after about 2 weeks, the color was yellowish brown at once. Meanwhile, all the cartridges have been replaced, a clean compressed is no longer even in black and white with no stains possible. Some passages are simply not printed. Need to buy a new printer now probably. hands off!!
