Example Input: In all fairness my friend absolutely loves this product.  I purchased it based upon his suggestion.  Unfortunately, the smell (oil I am assuming) of it cooking made me feel ill.  Even though the product cooked perfectly, the smell lingered in my microwave for well over a day.
Example Output: 2

Example Input: I had high hopes when I purchased this produce, shipping was amazingly fast and I've tried it a few times. I don't enjoy the taste, and since I don't sweeten my tea, it wasn't that great, and it did nothing for my sinuses. Will not purchase again but I do recommend the seller.
