Example Input: Not knowing what to expect I decided to take a chance since it wasn't that expensive.  I was pleasantly surprised by the quality of the caviar.  I put this stuff on just about anything I could and it was amazing.  I don't know too much about caviar, but for this price I don't think anybody can complain. 
 Polarity: Positive
Example Output: True

Example Input: I bought this for my very smart lab mix rescue when she was about 6 months old. At first she wasn't interested, but once I showed her how it worked, she got down to business. She worked at that toy all day long the first day, thougth she wasn't able to get all the food out. On the second day I gave her the toy, partially filled with kibble and went upstairs. In the 25 minutes she was unsupervised, she got the screw cap off, ate all the kibble, and destroyed the bottle. 
 Polarity: Positive
Example Output: False

Example Input: These are great - my entire family loves them.  It is a great addition to my son's school lunch - and I have the satisfaction of knowing it is a better alternative then the normal "chip" out on the market.  Great flavor - BBQ and Sourcream & Onion are our favorites!  Love the single serve bags - wish you could buy them at the store - but for now I will continue to purchase on Amazon...  because of the great service and varieties! 
 Polarity: Positive
Example Output:
True
