Ex Input:
Melitta's rich, flavourful product is a delicious treat comparable to coffees with a much higher price tag. It is a plus that the decaffeinated version does not sacrifice flavour. Highly recommended.

Ex Output:
5


Ex Input:
With any low fat or low calorie food, you're going to sacrifice taste of portion size.  With this product, you sacrifice both.  It's a good idea, which was done well with the Oreos and others in this series of "100 calorie" snacks, but I think you're better off with a single cookie from the regular Chips Ahoy box than a whole bag of these.

Ex Output:
3


Ex Input:
Even in the stores, they tend to be broken, but these on average are worse. Given the price per cracker, that makes them really expensive.  Love the crackers themselves. They are the best vehicle for peanut butter and jam that I've found.
