Example Input: These chips are very good. Wish we could purchase them in our area. Great chance to try them in this offer.
Example Output: Positive

Example Input: Makes great coffee for about 4 months. Cheaply made product. All pipes inside are cheap plastic. Even a $25 Mr Coffee has copper water pipes in it to carry the 190 degree water but not Keurig....all plastic water lines. Heat plugs the lines up in 3 to 4 months. Piece of cheap junk made to look pretty. Save your money
Example Output: Negative

Example Input: i've never written an amazon review before, but this product was so horrible i had to warn would be buyers; i can eat pretty much anything, but i had to empty out both bottles... it just tasted like colored sugar water (very thin), sickening sweet.. don't know if there was any onion flavoring.. the only reason i bought this is because i couldn't get ken's steakhouse vidalia onion dressing shipped in California.  So far, the worst product i have purchased on amazon.  Buyer beware, unless you like sugar water, then "drink up"..blech.
Example Output:
Negative
