The price was unbeatable, so I wasn't expecting the world's finest ink cartridges, but the blue ink doesn't work in at least one of the color cartridges. (I haven't tried the other one). But hey...I've bought ink from the printer manufacturer and from other third parties for much more money and had similar problems. This is the only problem I've had. The black ink cartridge that I've tried so far works great. I'll probably buy this product again.
Sir, I just installed a black cartage in my printer and have only used it once. I have no idea how long it will last, or if it will meet my expectations. It is smaller than the ones I'm used to buying, but for the price, it is still a good buy if they last for any length of time. To be determined as of yet.
