You never know when it comes to ink these days. It might be a godsend, but if you can get 4 cartridges for less than Canon sells 1 I thought I'd give it a try. It is great. The only downside is that the amount of ink is not accurate. He'll tell you that you're running low on supplies, but you'll have a lot more options. Just press "Continue Anyway” on your keyboard and keep typing. I've bought it 3 times so far and will continue to do so. To attempt. you will thank me
