After speaking to some alternative Epson compatible printer cartridges so my problems had (alternately detected, not detected ...), I have now decided to prefer to spend a little more money for it to get better quality and have been disappointed at all : super fast delivery (Amazon typical), potty installation and so far absolutely error-free operation. This is especially worth my few euros. Particularly pleasing is beyond the Amazon.com price for this product which fails lower by almost 10 euros as of the Epson Stores price. Completely satisfied.
