I understand the adage "less expensive." I thought I got a good deal. After several impressions, it starts to drool all over my Canon MX 870 printer. The printout is not sharp as the original cartridges. And my printer began to print shift. I'm disassemble, clean the ink, the printer head as the youtube videos, nothing works. Today I can not use my printer. And as it is necessary for my job I was forced to buy another. So beware and avoid like the plague.
