I tried it, but I just didn't like it.  Not a good tasting sugar substitute in my opinion.  I'd rather do without sugar than use this again.

Ex Output:
Negative


Ex Input:
I have a bichon and I thought this would entertain him for at least 15 minutes, but it didn't. He solved it quickly, within 5 minutes and looked at me as if to say, that's all?

Ex Output:
Negative


Ex Input:
I have tried every brand of stevia on the market and this is, hands down, the very best out there.  I use Nu-Naturals NuStevia for all sweetening purposes.  It can be hard to find even in health food stores and the ones that carry it usually charge a premium.  I was delighted to find it on amazon.com for a very reasonable price, even less when obtained through a standing order.

Ex Output:

Positive
