I have a Canon Pixma MG2120 which is about a hundred years old and to be honest the cost of buying new cartridges from Canon got me thinking about getting a new printer. Serious. I bought mine new for under $30. So a renovation seemed like a good option. But here's the problem - not all work well. The last ink set I bought didn't work right out of the box and I didn't have time to return it. And the pages come out with streaks or too little color. Simply bad. But I digress. As I said, when I found this product I was about to buy another printer. I grabbed my last chance and lo and behold! and so! They work just like Canon, only a lot cheaper! My pages are clean, colors are not smudged and I am very happy on vacation. Please do not alter your product - I plan on using you until my printer falls apart!
