[EX Q]: You cant go wrong with Rosa Monte Especial! this is one of the best yerbas in Argentina. Go for it. Seller did everything ok, in time and etc.!
[EX A]: Positive

[EX Q]: I have tried various brands of stevia, but I always come back to NuNaturals. I buy the 12 ounce container because I use it to sweeten everything. If you have a sweet tooth as I do but don't need the added pounds, then this is the ticket for you. I drink a lot of tea, and this is my sweetener. A lot of other stevia brands leave a bitter after taste, but this is the best that I have found to resolve that problem. Highly recommended.
[EX A]: Positive

[EX Q]: I thought this was a Jamaican blend or roast, but turns out it's simply a heavily flavored coffee. The flavor tastes artificial - like fake maple syrup flavoring. We have three coffee drinkers in our house and none of us could get past the first few sips. Now I have to find a home for the rest of it so it doesn't go to waste.
[EX A]:
Negative
