Example Input: I've tried a few different flavors of Switch and this is my least favorite. (My favorite is the cherry.) Unfortunately because I didn't enjoy this flavor I didn't find it as refreshing as the others. I quickly handed it over to my son who does like kiwi berry flavors and he did like it a lot. Of course, since it contains enough vitamin C for a whole day, I felt just fine giving it to my child, too. No preservatives, no added sugar. I like the carbonated soda product a lot, just not this flavor. However, the biggest flaw with this product is that it's too expensive in my opinion for the little cans you get. Rounds out to about $1 per can. Less than you pay often with a vending machine but twice what you pay for a flavored water or vitamin C juice pouch when you buy them in larger quantity. Not worth it. :(

Example Input: The cookies came sealed and seem to be high quality in there ingredients. The only thing is they just don't taste that good. My girlfriend and I thought these might be a good dessert-like option while doing the Paleo diet, but after trying one of each kind over a couple days we just don't find ourselves going back for more. I would much rather not have a dessert and really check that box on a cheat day than being left wanting more after eating these. If you have a true gluten allergy, maybe this is a good option for you but I'm not a believer.

Example Input: Despite what some think there is a ton of fillers in here (see the ingredient list on the Omaha site), but.... that is not a bad thing in this case. They are not unhealthy fillers and these are very delicious. Our kids just love them. We serve one ball as a serving as that is the perfect healthy carb portion for a meal. 1 piece has the following nutrition just in case you are wondering: Calories: 120 Fat: 4.5 Trans Fat: 0 Sodium: 270 Carbohydrate: 17 Protein: 3 For our dinners we try to keep our carb side to under 5 fat & 25 carb. This fits perfectly & the taste is superb. Baked in the oven, they come out crispy on the outside and moist and tender on the inside. All with no grease. We now keep these on hand instead of french fries. I know they cost more, but they taste better and they are so much healthier. We wait for one of the sales and buy several boxes at a time.
