Example Input: Due to health issues, my husband is newly required to eat a gluten free diet. He acted as if he was on death row. Finding this product has help immensely. I can make him pancakes with fresh fruit and he doesn't feel he is being unfairly punished. Also, my neighbor was faced with a similar circumstance. I shared one of the boxes with her and she is now a fan! <a href="http://www.amazon.com/gp/product/B004391DK0">Bisquick Pancake and Baking Mix, Gluten-Free, 16-Ounce Boxes (Pack of 3)</a>

Example Input: I previously tried other matcha products and was generally satisfied with the quality but not the price.  I decided to give Pure Matcha green and rooibos a try because the price seemed to be very competitive.  The quality of Pure Matcha's products surpasses that of all others I have tried- stays fresh, has a consistent texture and tastes great.  Both the quality and price are better than others that I have purchased for the same quantity.  I highly recommend Pure Matcha and will continue to purchase.
Example Output: 5

Example Input: I have purchased these gummi candies in the past and not had a problem, but these strawberries tasted terrible and I ended throwing them out.
