This was a disappointment.  I use other products from this line/manufacturer on a regular basis.  I bought this item as a convenience to carry liquid Stevia in my purse.  The first time I went to use it, the liquid was a dark color...almost black..and I had to throw out the latte I was trying to sweeten.  All the manufacturer's other liquid products are clear, and, in fact, this is titled "clear liquid".  It must have been outdated/spoiled. I had already thrown the packing out, so don't know how it was dated.  I tried calling the Amazon supplier, but the call rolled into voice mail.  It's not enough money to spend time following-up, but it was disappointing.

Ex Output:
Negative

When I got my dog I did a lot of research regarding dog food and dog food ingredients. There are high quality dog foods like this one out there, but you probably won't find them in regular supermarkets. While this food may be more expensive than other dog foods, it is well worth it. Innova Evo is one of the foods that were NOT affected by the recall. Also, the ingredients are healthier, and don't have high wheat/grain content or nasty additives.  My Doberman used to have a lot of dandruff and had some skin problems. Also her poop was really mushy, almost diarrhea. When I finally switched her to Innova Evo Red Meat I'd wished I'd done it sooner. She doesn't need to eat quite as much, and her coat is beautiful! No more dandruff problems and her skin is great.

Ex Output:
Positive

I find the gluten-free Bisquick pancake mix to be just as easy to use as the original Bisquick, and I like the flavor just fine (not much different than regular Bisquick).  It's easy to make the pancakes, just add milk, oil, an egg, mix, and pour on the griddle.  Cooking time seems to be about the same, and the consistency of the pancakes is just like regular pancakes.  I would definitely recommend this mix to anyone needing gluten-free products.

Ex Output:

Positive
