I ordered BCI-3e ink jet cartridges for my Canon i550, but that is not what I received. I did receive three black BCI-3e cartridges, but the six color cartridges where BCI-3 color cartridges, not BCI-3e cartridges. I get printing errors all the time now due to the incorrect color cartridges. I don't print much, so when I discovered this problem, it was too late to return. Please beware of this seller, they send the wrong product!!!
