Example Input: This is the best tasting stevia powder I've tried. Most other powders have a weird after taste but this one doesn't. I recently bought a 5lb bag of it online and I'm making my way through it.
Example Output: Positive

Example Input: Well packed. Few are broken but it is understandable. The cookies are tasty and the notes are interesting. My friends and I really enjoyed it! Thx!
Example Output: Positive

Example Input: I added 3 tbsp of sugar and half tsp of pure vanilla and a pinch of alum free baking powder and coconut oil for oil and it came out soo good. My son loved it . I liked it too. The fact that it's all the major allergens free makes it better.
Example Output:
Positive
