Example Input: I have managed to find these crackers in other countries on our travels but had run out. I love that they are individually wrapped small packets in a stay fresh container. This makes them great to carry in my purse, take to work or on airplanes for snacks etc. Also love that they are not overly salted like so many American brand crackers. Company that shipped them did a great job - fast too!
Example Output: 5

Example Input: This product has a strong after-taste of Crayola crayons!  I am in the process of trying different brands of coconut oils for cooking purposes.  Upon opening the plastic container, the aroma of crayons immediately fills the room, and this flavor permeates the food that is cooked in it.  I suspect the source of the problem is the plastic used in the plastic container as I have not experienced this with any of the other brands purchased.  To date, my favorite coconut oil is distributed by Barleans.  The flavor is fantastic.  However, they do not supply a gallon-sized tub,and Dr. Mercola has the best product in that size category.

Example Input: I use this in and on meats, fish, poultry, vegies, all purpose dip et al. It's cheap and very very special. I gave big bottles to family/friends at Xmas years ago and they are all  hooked. You won't be sorry you brought this sauce into your kitchen.
