Example Input: This is easily the best potato chip that I have ever had.  Look at the ingredients:  Ginger and 3 types of hot pepper.  How can you go wrong?  Obviously, not for you if you don't like spicy food. But, if you DO like spicy food, you'll probably love these.  They have that hot-with-a-hint-of-sweetness flavor combo that is prevalent in a lot of Thai food.
Example Output: 5

Example Input: I bought these for my son to take to work for lunch. Apparently his co-workers found the smell so offensive they asked him not to eat it at work again. Maybe it was a bad batch...
Example Output: 1

Example Input: I bought this before I purchased the MXL Micmate. It is plastic, and very cheaply made. I felt like it would break very easily, and would not be something that would last me a while. So then I bought the Micmate. It is solid metal, and is way better sound quality than this. I beg you to buy that over the Icicle. Buy the MXL used (Like New) from "TheMintMovieMan", a great seller and it is a great product. <a href="http://www.amazon.com/gp/product/B000VZ8WC2">MXL MICMATEC XLR To USB Preamp for Condenser Microphones</a>
