[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]: Chips are not as tangy as I hoped or expected. Poore Brothers is a better choice for the "hard-core" Salt N Vinegar fans.
[EX A]: Positive

[EX Q]: love it. eating it has got to be a ritual. taste is well balanced, nice and chewy without being overly sticky, leave a great lingering aftertaste. compared to gimbal's scottish dogs, these taste and feel more traditional, and much healthier too, given that only four ingredients go into them. out in the midwest, ann abor to be specific, i found these in the candy aisle for around $2.80 per resealable bag of 170g.
