In this task, You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

Example Input: At first the fan was great, very quiet. we have had it for just over a year now. recently two of the three fans quit working. we dont use it much so we were surprised to see it acting up. We also never received a remote control as advertised
Example Output: negative

Example Input: I purchased in June and hired an HVAC professional to install. After several calls to Nest support, it was determined that we had a faulty plate so we attempted to install the 2nd and again after several calls and a couple of hours, determined that that one wouldn't hold its charge long enough to install. In both cases, the window to return them had lapsed so I am out of $400 plus and then had to buy a regular thermostat to boot! Lesson here, do not buy this product until you are ready to install it!
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
