Example Input: 4.5 stars The vented bottles helped so much with my baby’s gas problems. Took half star off cuz they are diff prices depending on color, wished they were same prices
Example Output: positive

Example Input: Failed 35 days after purchase. First it couldn't make up it's mind about if it had a battery or not, and would only work if plugged in at all times, and then it just bricked. I used this as entertainment for 2 small children while driving across the country. It worked great when it worked. I had 4 devices connected to it and all of them streaming videos all at the same time without any issue 95% of the time. Of course when the signal drops, it slows down but if it had at least 1/2 signal, it would keep up with everyones demand. If I had good signal at my house, I would consider replacing my cable internet with this.
Example Output: negative

Example Input: My dearest friend lost her husband of only 9 years and I was very excited to be able to send her this gift. When she went to put it on the clasp broke. Very upsetting!!
Example Output:
negative
