Example Output: negative

Example Input: I'm very dissappointed. Look at the picture of the product and look at what i recieved!! It's not even a shirt and a cape. I got this bib tie on looking thing that doesnt even sit on a puppy properly.
Example Output: negative

Example Input: Received this item a few minutes ago and was glad to see it arrive. Put it in the printer and immediately received an error message that the cartridges we're both low. The photo shows the computer readout indicating the color is just below half full and the black is almost gone. These are brand new and haven't been used yet, because the printer has a feature and won't print with cartridges that low. Very disppointed! As I continue to contact Valuetoner, I will update my review if handled.
Example Output:
negative
