Query: Double-check for compatibility.

Not compatible with Canon MX700, for one, and I found that out the hard way. Seems I'm not the only one to have this trouble. Amazon was prompt in issuing me a refund, even months after I ordered this item, but don't trust the rubric on this page. I'm baffled at how they can even pretend this cartridge works for such a wide array of printers.
