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: My 3 year old granddaughter loved this puzzle. It is very colorful I would definitely recommend this puzzle. It is very well constructed.
Example Output: Positive

Example Input: I've now been through three of these cords. they seem to last around a year before just dying. The first two eventually had fatal connection issues with the piece that connects to the computer, however my third one has just died and is actually not getting any power from the wall. The little indicator just fades out, and now won't come on at all. Yes it's a lot cheaper than the other cords, but I'm just not sure its better. I know lots of people have problems with the apple cords as well.
Example Output:
