Error messages and no identification

The delivery was fast and the price low.
Have therefore bought two.
But:
A blue cartridge expired already in eingeschweisten Zusatnd
The cartridges were not running ease to use and produced error messages. The first three colorful cartridges were recognized, but I can never make an expression as the printer only works with all.
A black cartridge gave the error message "Problems Ink System" and "recognized No Cartridge" the second.
In my search for solutions rebooting was the only approach quickly carried out after the mains cable. Many forums claiming it would be at the printer manufacturer, the software by the not original - "punished" cartridges. But I rather think that these cheap refilled cartridges are poorly produced. After a few days, I have also the distributor does not reach by phone and was annoyed. With Amazon, you have me at once provided a return label when telephone contact and then refunded the money.

Annoying waste of time if you certainly needed the printer, which is very risky.
The 5 star reviews are here comical way by some people who have only reviewed this product.
It may be that I had bad luck.
Quality assurance should the sellers are the heart, no one else buys the scrap.
