Ex Input:
I have ordered numerous teas, potions, lotions and other remedies...BUT have never had a lack of product in an order that was sealed.  The tea bag wrapping in question was sealed without a tea bag inside.  I would have said something sooner, however...I only tried these when I had a sinus infection and the last 3 times I tried to use one...the sealed pouch was EMPTY.  BEWARE!

Ex Output:
Negative


Ex Input:
I loved this tea! It is refreshing and delicious with or without sweetener. A great buy! I would definitely recommend this product!

Ex Output:
Positive


Ex Input:
Very nice product.  It is not a Mounds bar, but it helps satisfy the urge.

Ex Output:

Positive
