Example Input: Hard to get husband to eat breakfast before school.  He takes two bars now and is very happy to do so.  It is often hard to find flavor in local grocery stores.  So again, Amazon.com came through with a reasonable price.  Now, I came keep the husband's breakfast ready as he runs out the door in the mornings.  I often like to have a bar in the evening as a night snack.
Example Output: 5

Example Input: The pineapple coconut combination is refreshing. I especially like that there is no added sugar. This is a welcomed change from other brands.
Example Output: 5

Example Input: When I read the description of this it said mini - these are regular size.  Tastes great but my 86 year old mom wants the mini ones and I have not been able to find the smaller dine size ones.
