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: I admit that I fully expected to dislike this product, and approached it with a dismissive attitude - something that's this trendy can't be any good, right? well, I was wrong. The ONE coconut water is refreshing, delicious, and just barely sweet. Really wonderful stuff. The hint of pineapple adds a little bit of acidity that enhances the basic taste of the water. i bet this would make a great summer drink too, but I only had one so I didn't get tot try that. My problem now is that it's been out of stock, so I can't get more.

Example Input: I am a huge fan of Stinger products. However, these little gummy gels do nothing as compared to the Stinger Honey Packs. If you are a road or mountain biker and need a good burst of quick energy to keep from bonking on that last hill, these will not help. In fact, the only benefit that I (or any of my riding buddies) have found is that they make your mouth water. Conceivably, this could help with water consumption when riding through the desert (Moab, Fruita). It is my guess that these are not intended for exercising. Maybe, people just use them at work to keep from eating Starburst or something less healthy?!
