Example Input: Either I got 15 tubes that came from a bad batch lot or they are not selling the right Harissa. I bought 15 tubes thru Amazon from Parthenon Foods and used 4 of them so far and after putting the whole tube it still isn't spicy at all. Normally a whole tube would get you to sweat a bit!!!!! This seems to be a case of false representation. I buy these tubes in Canada at the grocery store all the time when I am up there and they provide a nice kick and spice (as they should). What's up with dat?
Example Output: 1

Example Input: I love these crackers!  Perfect snack for when I need something salty/crunchy instead of potato chips or other greasy snack.  I eat them a lot to hold me over between meals.  The price on amazon is great compared to my local markets.  Highly recommended!
Example Output: 5

Example Input: My two cats used to love this formula, but I guess they got tired of it, or maybe the formula was changed ... I only feed it occasionally now.
