I usually buy ink for my Canon MX922 from my favorite shop, but since I use more black ink than color ink, I don't need the $80+ full OEM kit every time. Given the low price and some reviews, I was hesitant to pull the trigger for this purchase. The price looked too good to be true and some reviews cited compatibility issues, normally the printer wouldn't recognize the cartridge. I figured if even one of the whole pack worked, I would still save money, and if none worked, I'd get a relatively cheap lesson. But they arrived quickly, the packaging was easy to use (I tried a few recycled cartridges that were usually dirty) and the first worked, then the second and so on. I mainly use the printer for office prints and don't notice any difference between them and Canon EOM ink - except for the price! When they run out, I'll order more.
