My experience was that after installing 3 cartridges I only had 1/3 to 1/2 cartridge advantage, after that they stopped printing; I had to put in all the new cartridges. very expensive and I was even worried that my printer might have been damaged at the point of the cartridge as it never refused to print or told me the printer could see NO INK at all! He wouldn't even let me check the printheads without putting in new cartridges. I don't know if it was just a bad badge or if they are just NOT reliable. They worked for about 10-14 days, after which they stopped. I can't afford to waste money and time on such things. Let's see if the seller responds.
