Ex Input:
I was excited to see that Amazon is selling 100% Kopi Luwak. However, these beans were a huge disappointment because they had no aroma and flavor at all. I'm guessing that they sent stale beans because there was no roast date printed on the bag.

Ex Output:
Negative


Ex Input:
This soy sauce is the best we have ever had.  Thanks to Amazon, we were able to find it again.  It makes a big difference when using this product.  Thanks again

Ex Output:
Positive

I bought this product last week for our dogs, within a day both were vomiting and refusing food. Our larger dog is doing ok since we stopped feeding them but our little guy is not. Taking both to the vet tomorrow along with these treats.
