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 have used this product multiple times.  In fact, I purchased four tubs of the gold and silver luster dust (2 each) five years ago and I am JUST NOW running out!  I use this stuff to gild all sorts of things for Renaissance themed banquets - including gilding an entire roast duck and then, using vodka, painting filigree designs onto it!  The clients thought it was prop food it looked so beautiful.  I can't recommend this stuff enough!
Example Output: 5

Example Input: This is one of the first crackers I tried, yes if your gluten free it may work but doesn't hit the spot like regular crackers.  There are MUCH better alternatives for you.  The crackers are chalking tasting and no one in the family liked them.  We did find that Glutino nows sells a VERY good Table Cracker.  Little more expensive but they are great for your soups, chilis, meatloafs and taste just about like a saltine.  You can't go wrong with Table Crackers.  Also try nut thins - had more compliments on those crackers then with these. Don't waste your money on them (regular, cheese or veggie) YUCK!
