[EX Q]: These truffles are not as great as they are made up to be. I thought for the price they would have a greater taste, but they didn't have much taste at all. They are not worth the price, but had to find out for myself. I will not be buying truffles again, and I'm not going to spend over $10 for a fresh one.

[EX Q]: NuNaturals Stevia is the only sweetener that I use in my beverages and cooking. I have tried other brands and this one is the best! It hasn't any odd taste, and tastes better than sugar to me. I buy the large 12 ounce container and it lasts me for months! I only wish they would put this in more products sold at the grocery stores. There is a soda that has stevia in it that I purchase at a health food store called Virgil's Zero and it comes in different flavors...it is great and I don't have to be concerned about the sugar content that is in traditional sodas. This product is great and I think is the best of stevia products on the market.

[EX Q]: This is a great buy.  I love this hot chocolate because it is very low in sugar and has a good taste.  It isn't messy like regular hot chocolate as it is all dissolved before it hits the cup.  Would buy again.
