Q: This is the best tasting stevia powder I've tried. Most other powders have a weird after taste but this one doesn't. I recently bought a 5lb bag of it online and I'm making my way through it.

A: Positive

Q: The first time i filled it, it droped on my hard floor and the bottom shattered. My doggie didn't even get a chance to try it out!

A: Negative

Q: What am I missing?  This mix creates a pretty much tasteless pancake. I've tried adding vanilla and cinnamon. I use real maple syrup on top. I cook them in fresh bacon grease. The pancakes are still, just, blah. It's like they absorb and negate the flavors.  The pancakes cook ok. The texture is fine. Just absolutely no flavor.  Won't get this again. Considering pitching the rest of what I have.

A:
Negative
