Example Input: Umbra Coretto 24 to 36-Inch Decorative Tension Rod, BlackThe rod is really good looking. However, because it is so thin, the weight of my shower curtain keeps causing the rod to come loose. If I had any idea, I probably would not have bought the rod. However, my shower is at the wider end....so maybe a person would have better luck if their shower is closer to 24".
Example Output: Negative

Example Input: I used this for taping while we were opening gifts for christmas. The remote features are great. This product makes video recording easy and fun.
Example Output: Positive

Example Input: I found Man of La Mancha to be quite confussing. The plot is so crazy that it is hard to get a grasp on what is happening until halfway through the book. One you do figure it out, it is rather humerous, but not one of my favorites by any means.
Example Output:
Negative
