Had me about 10 times J. refill purchased, but was absolutely not satisfied!
New original cartridges were needed!
So I searched and came across here on this double pack.,
My HP DeskJet 930C is still working properly - and that for over 14 years.
So this double MULTIPLE ordered! Never had problems with the print quality!
For me, this original enough Tintenpatronenset about 2 years.
VERY recommendable.
