Example Input: Deceiving!! First off if mix correctly by using 2 tbsp of mix with 7 oz of water it taste great. If you buy the packets of this which contain 2 tbsp it taste great. The instructions on the canister says 1 tbsp. And it says you get 20 servings. Wrong. You get 10 servings if mixed correctly. So there is no bulk savings. Ripoff.
Example Output: negative

Example Input: The material doesn’t look cheap, I liked the zipper, it works smoothly. Perfect for all my accesories while traveling, I can keep my charger from getting scratched when I am flying all the time. It is a great protective product.
