[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.
[A]: Positive


[Q]: Busy Buddy Kibble Nibble has been a great toy for my dog, but Tug-a-Jug was not.  Within 10 minutes, she had gnawed the "challenge" rope into 6 pieces.  Maybe it's good for an older dog but definitely not for my vigorously chewing 8-month-old puppy!
[A]: Negative


[Q]: We use gluten free bisquick for many different things - biscuits, pancakes, etc.  Tastes good & lets us serve our kids that are gluten free the same thing as the whole family.
[A]:
Positive
