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 purchased this as a present but it doesn't come As shown in the picture.  It is little white bags with the flavor written on them.  Someone receiving it as a gift wouldn't even know what it was unless I explained it to them. Will be returning.
Example Output: 2

Example Input: I like this item because it enables you to freeze baby food in larger portions than ice-cube trays, which is a good thing if your baby is a little pig like mine is.  My biggest complaint is that it is difficult to get the frozen items out of the tray once they are done.  I usually have to run it under hot water for a few minutes, which is not a big deal but just one more step.  Also, the price is very high for what this is.  I could use a second one but at this price I'll make due with the one I've got.
