Example Output: positive

Example Input: Don't waste your hard earned money. It doesn't work. The thing came with a cable to connect the AUX connection only, which did not work. It had connections for digital and usb connections, so I ordered digital and usb cables. It still doesn't work. The only thing that works is an LED light.
Example Output: negative

Example Input: I have never written a negative review for any item I have purchased however the quality of this phone case is so poor that it was cracked when it arrived and I returned the product to get another one and I have never received a replacement. The color and style of case are wonderful however if it is crumbling apart then it can’t protect anything.
Example Output:
negative
