Example Input: This charger is just the right length to be used in my car. The braided cord allows for the durability to be handled with some force. I am very pleased with the charging speed this cable provides. I will be ordering different lengths from this seller. Top notch!
Example Output: positive

Example Input: This item arrived in the mail a MESS! When I opened the package, I stuck my hand into goo. Not only was the lid not screwed on properly, but the container was actually cracked! See pictures! And it says “no returns”. It’s unusable! All of the liquid is in the envelope or dripping off the bottle
Example Output: negative

Example Input: This didn't release Melatonin slowly over the course of 7 hours. I woke up after about an hour and a half each night and then would be completely wide awake. I actually felt wired. Such a waste of money. If it actually worked like it was supposed to, it is a genius idea.
Example Output:
negative
