Input: Consider Input: I'm presently on a diet and I was at my Fresh and Easy Neighborhood Grocery looking over possible diet foods. I wanted things that were tasty, non-fat and low in calories. I came home with about a dozen items. That's how I discovered the Tillen Farms Pickled Crispy Asparagus. Well, I've always liked asparagus anyway and I've enjoyed several brands of pickled asparagus. This Tillen Farms brand is really, really good! It's the best I can recall. There's an excellent flavor and a big clove of garlic down in  the bottom of the jar which I'm looking forward to eating. I can't believe how good this asparagus tastes and right on the front it says "only 60 calories per jar!" Now this is my idea of a good diet food!  Gary Peterson

Input: Consider Input: This product is good. However, I feel the carbonation is a little more emphasised over the fruity flavor. Unless of course carbonation is really wanted. I didn't find the juice flavour as good as Juicy Juice. And the cost is ~50% more per ounce for Switch vs. Juicy Juice for my region.  I would say that for everyone who is interested in this product... let your taste buds be your guide.

Input: Consider Input: I've been very pleased with the Natural Balance dog food. Our dogs have had issues with other dog foods in the past and I had someone recommend Natural Balance grain free since it is possible they were allergic to grains. Since switching I haven't had any issues. It is also helpful that have have different kibble size for larger/smaller sized dogs.
