After seeing all of the good reviews for these refurbished color cartridges for my HP printer, I bought 2 of them. The first cartridge printed no color at all. The second one printed all color as yellow and green. Horrible. I have not had any good luck with refurbished color ink jet cartridges for HP from any 3rd party distributor. These were by far the worst. I could not even use them. What's worse, I bought them as backups, did not open and test them when they arrrive, so the return period has long since passed. This is my first unhappy purchase ever from Overstock. I will say that I purchased the HP 45 (black) at the same time and those seem to be working fine.
