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:

Ex Input:
This hot chocolate tastes like hot sugar water with a pinch of coco in it. Although, even the sugary taste is weak, and tainted by the flavor of the artificial sweetener sucralose. The consistency is watery and bland. This is when I made the 8oz cup as directed by the directions on the box.  I do not recommend this product.

Ex Output:
2

I'm trying to eat healthier and one of the things I really love is chips and salty snacks of all kinds!  These Popchips really do the trick of satisfying my craving. Though I don't really care for the pepper flavor, I like all of the others.  I will buy these again.
