Example Input: This item is not as described in the product description and did NOT work for me. I used it according to instructions that was included. It may have been intended for someone else but not on me! I think it caused a reaction. Did get refund so no worries there. Hope this helps.
Example Output: Bad review

Example Input: The sound is horrible. You have these little 'headphones' that are supposed to go on over the ears and they don't even fit my 12 year old. He was so upset because it didn't work for them. No matter how tightly you put these on, his glasses pushed them off at every turn. They wouldn't stay put. Don't waste your money. I returned mine immediately. Bummed kids = big headache.
Example Output: Bad review

Example Input: If you do business with Amazon this is not the book for you. There should be some sort of disclaimer that it is strictly aimed at large commercial enterprises. The basic thesis - small companies have been getting lost in the maze of bureaucracy and tax havens over recent years and if they didn't get rid by now it's because there are no jobs to be found. That said, many ideas were interesting.
Example Output:
Bad review
