Example Input: The candy arrived with some white waxy stuff on it; almost as if it had partially melted at one point.  Tasted chalky.  Not interested in a partial refund.  Next time find a way to make sure candy is not stale.

Example Input: It always amazes me that there are not dozens of reviews here extolling the fine qualities of this tea.  I have drunk it pretty much every day for the last five years and I never get tired of it.  It's an excellent morning tea, is smooth without being insipid, and is almost impossible to ruin by oversteeping. Just use decent water.  I like a little stevia in it, as I'm a wimp. It brings out the natural sweetness of its malty, slightly floral style.  I just bought another two pounds.
Example Output: 5
