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.
