Example Input: This stuff sounded perfect...way too much red dye and no taste according to me and my 3 friends who tried it...kind of salty.  Basically, I would stay away from it.  I am tempted to toss it out, but paid too much to feel right about it...
Example Output: 2

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: This mild semi-soft/soft cheese has a range of subtle flavors that I have yet to find elsewhere.  The price is worth it, though I can't afford to order it often, but the combination of this cheese with a really good white wine is truly a culinary delight!
Example Output:
