I would like to give a zero star if I could. I bought this HP78 ink cartridge and found the yellow and green ink has been dried for a long time when the package was first open. All the color prints look pinkish red. I tried to contact the seller through the Amazon email system because they "guarantee the quality". The seller never responded. I have to toss this one in trash and feel real sorry that I bought this junk cartridge from this irresponsible seller. I should have read and listened to the other negative comments that preceded my comment. If you think this reduced price is cheap, stop, it is not cheap for a useless cartridge. You can get a much better one for the same price from other sources. Again, I strongly recommend that buyers beware, this product is a piece of real junk and the seller will play deaf ear with you!
