Example Input: This variety pack is perfect for when you want something crunchy and salty. The selection of flavors were great choices for me - I liked them all. The portion keeps you from overeating, and they are healthier for you than potato chips, even the baked ones. I recommend these and will be buying them again and again.
Example Output: 5

Example Input: I love this coffee. I do wish it came already ground as I don't have a grinder and use a blender instead. But it's worth it. Many flavored coffees I've tried only seem to have a flavored odor that doesn't reach the coffee, but this one manages both.
Example Output: 5

Example Input: If you like Orange Crush you may become a fan, but it's too much of a hybrid for me. The main two ingredients are reconstituted apple and grape juices. It contains something called Acerola juice, which is high in Vitamin C (and indeed the can contains 100% of your C and 20% of your A). The sugar content is high---34 grams---which brings the carb percentage up to 12% for the day and the calorie count to 140. I think it tastes too acidic for anyone who is watching carbs and calories to be willing to "spend" them on Switch, which almost tastes like carbonated TANG. I've tried the Ooba drinks, and they are much lighter and more refreshing. Guess I'm just not ready to make the Switch!
