Like almost everyone else, I am very disappointed with printers and their inks. The color ends even if you have never used it, and then black is not enough. This looks like a scam. I have had questionable experiences with other brands of ink and have been reluctant to try them. But the reviews looked pretty legit so I said fuck it. So far they've worked well in my Canon Maxify (it's a good printer but with some of the most expensive cartridges!). I don't usually write reviews so I don't know if that's helpful, but in the end I'm really happy. I use it for my business and the copies need cleaning and this ink works just as good as Canon 1200 ink just a lot less money.
