Example Input: Never received the lights. Email said they were undeliverable? Which is odd because i received other packages from Amazon that day and someone was home all day. Ill look elsewhere.
Example Output: negative

Example Input: I used them one time and pulled them out of my phone and wire went everywhere and now they do not work. Biggest waste of money and would cost me more to send back.
Example Output: negative

Example Input: I liked the variety of flavors of juice this product had to offer. My children did not get bored with the same juice every morning. The size of the bottles were perfect as there was just the right amount inside. The quality and flavor of the juice was also very good, I would recommend this product to others.
Example Output:
positive
