[Q]: 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.
[A]: negative

[A]: positive
