Example Input: I have tried a couple of the other Switch flavors, and I found them to be very disappointing.  This variety, on the other hand, had excellent Kiwi and Strawberry flavors.  However, I emphasize FLAVORS because that is where the Switch drinks get gimmicky.  They are all marketed under the flavors/juices that appear WAY DOWN on the ingredient listing.  The several varieties that I have tried all have apple and white grape juice as the top ingredients.  This seems like false advertising to me, since those juices are clearly not as appealing.  Anyway, this drink is all about the marketing.  The price you are paying for 8 ounces of carbonated juice is clearly an extravagance, and I wouldn't do it again.  Save yourself some money and visit the juice aisle at the grocery store.
Example Output: 2

Example Input: I love this product! It is the best natural sweetener I have ever tried, and I have tried many. You can use also as pancake syrup or as a substitute for honey on your peanut butter and honey sandwich. It last a long time, and is a good value.
Example Output: 5

Example Input: Taste like tang, only more expensive.  I'm not a fan of tang.  If you love tang and want some convenience, this just might be the drink for you.
