Ex Input:
I heated these up in the microwave, and they do not microwave evenly. some will be burnt and hard as a rock when others will be just right. since you dont get very many in one bag, and since about 1/3 dont cook right, you barely get any pork rinds and throw the rest away. Maybe I am not cooking them right, but i followed the directions...

Ex Output:
Negative


Ex Input:
I first tried Britt dark roast when I was In Costa Rica.  It has a lot of rich flavor, but it is not bitter at all.  I've bought it by the case ever since.  It's really no more expensive than those "gourmet" brands you find at your local store.  This is simply the best coffee I've ever had, and I've tried many supposedly special ones over the years.

Ex Output:
Positive


Ex Input:
These are not the greatest.  Thought they would be great to have on hand when guest come.  Not so.  They were not what I had expected.

Ex Output:

Negative
