Example Input: The pink balloon was damaged out of the package. Due to the position of the damage, we couldn't inflate the pink balloon at all. That's 1/6 of the price+postage cost down the drain. Not to mention the wasted time and disappointment. For a such expensive product, we really expected better. We inflated 3 undamaged balloons, they worked fine so far, but I guess the 1/6 damage rate is simply to high for us to ever consider purchase this product again.
Example Output:
negative
