Works great! I have two other similar products and this is by far the most powerful. Especially for the price! Shipping was quick and easy without issue.

Ex Output:
positive


Ex Input:
The book is an easy read. The book is full of fabulous thought provoking questions to ask yourself. It is good for building a mindfulness practice...helps with weight loss, healthy eating, finances, relationships, etc. Elizabeth has a great pod cast called Primal Potential...excellent! The book was just what I needed when I needed it. She is encouraging and straight forward all at the same time. I have re-read the book as well.

Ex Output:
positive


Ex Input:
The story is interesting and I did buy several, hoping the next one would be longer than a chapter's length. Sorry but 30 minutes read time is not even a novella and I have read short story's that were longer.

Ex Output:

negative
