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.

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

The good news:  Very easy to make, tasty good noodles, a few veggies  The bad news: 1130 mg of sodium (about half your daily allowance) -- Yikes!  Notes: 290 calories, 0 mg Cholesterol, 2g fiber, 2g sugar, 7g protein, 11g fat (6g saturated fat)  These noodles are tasty, the broth is OK, there are a few veggies sprinkled on top.  Pour in boiling water wait 3 minutes (or longer) and you're done.  A good, quick, hot lunch when you're in a hurry.  But don't eat too often as the sodium content is incredibly high and would not be good for you.  OK once in awhile, though, unless you're on a sodium restricted diet, in which case, why are you even reading this far? ;)  Tip:  You can probably reduce the sodium content by pouring off the liquid after preparing and eating just the noodles and veggies.  Or add your own healthier liquid broth, even, if you wish.  Also, you can let this sit for 6-8 minutes of even longer and it will be good and still very hot.
