Example Input: I thought I was purchasing a high quality item but it's not all that. The chocolate is very sweet and as you chew on this product you can tell the chocolate is loaded with sugar by the crunchy texture. I'm going to say it's not worth the money and I'm not satisfied. At the same time of purchasing this product I also bought Sunmaid chocolate covered raisons which I rate from a 1-10...a 10. Now we are talking about yumminess!!!!! So customers...if you are going to choose...let it be the Sunmaid...you won't be dissappointed
Example Output: 2

Example Input: Kind of  a ripoff.  I bought the theater box instead of the 5 piece candy bar version and that turned out to be a big mistake.  Each box has only 8 or 9 pieces and they are randomly filled so you are not guaranteed even 1 piece of each flavor.  One box had 6 green pieces and 3 black.  A better value is 20 pack of the original 5 piece bar.  This theater box is sold by weight (4oz) and not volume.  The box is about 90% empty- Ripoff!
Example Output: 1

Example Input: The flavor of this coffee is good, it has a nice balance of Vanilla without being too strong.  It's not the boldest coffee, but it's a nice afternoon treat.  That being said, I have had problems with several pods.  When you hold them up to the light, you can see that there are grounds outside of the filter portion of the pod.  This causes a cup full of grounds when you brew the coffee, and also clogs up the pin at the bottom of the pod chamber.  I'd say about 1 out of every 5 or 6 pods has this problem.
