Task: Sentiment Analysis
Input (English): To my suprise, these cartridges are not actually for the Brother MFC 7840. They do NOT have the correct markings on them. I found this out when attempting to install them onto my printer. They fit, but there is no ink in them at all. The real problem is, and even more disappointing, how ridiculous it would be to send two packs of these back, only to then find that they didn't work either.
Output (English): Bad review
