Example Input: For the first few days I absolutely loved this case it worked great, then on day 5 the charging port broke and the case became useless, I was very disappointed because I was about to order 3 more for my family, I will now seek another option
Example Output: negative

Example Input: Bought for preteen daughter. Easy to use. We put curl cream in hair while wet, then put these in her hair and kept them in over night. Curls looked great. No tangles when removing. Great quality for price. Delivered quick.
Example Output: positive

Example Input: I wouldn't recommend this kit. First of all, it doesn't come with enough bags to put the beads in. The chart symbols are almost impossible to see - I had to get out a magnifying glass (seriously). Also, it's very difficult to tell the difference between some of the symbols. Some of the beads are different sizes so they get stuck in the tray. Need I say any more!
Example Output:
negative
