Ex Input:
This hot chocolate is pretty blah. Not very chocolatey and certainly not very strong. It's not the fault of the Keurig -- the Cafe Escapes Dark Chocolate is way better.

Ex Output:

Ex Input:
Was looking forward to this drink but was put off by its sweet soda-like taste.  Maybe it's an acquired taste? I'm not sure  but the high calories don't make me want to try.  Looking forward to a diet version.

Ex Output:

Ex Input:
This is the worst flavored coffee I have ever tried.  There is no aroma or flavor of Chocolate/Raspberry to this coffee bean at all.  In fact the coffee tastes sour.  I too am sorry I couldn't buy just 1 lb. to try it first -- Now I am stuck with this awful coffee I cannot return.  SO, BUYER BEWARE -- NO RETURNS!
