Instant Ink ("II") is a POS. If you get a subscription to II and then cancel it, you will no longer be able to use ink by a manufacturer other than HP. I don't care if I had to return the II when I canceled it; that's no big deal. But to make me use only HP ink? That's quite a bit of BS. I did order HP ink because my printer stopped printing. (Luckily I have a Brother printer that's hooked up and printing (with 3rd party ink.)) Once the HP ink runs out, I'm going to try to refill the cartridges with other ink. Hopefully my FU to HP works.
