Example Input: At first, I was concerned about ordering Babka online but I kinda missed this one. As I tasted it the only thing I could say was : "wow". I will order this again for sure.
Example Output: 5

Example Input: I love the product. But, the bottle design is terrible. In order to get the last 1/3 or so of the body wash out of the bottle in a timely manner you would normally store the bottle upside down. With the pointy top that is impossible. So, you must stand in the shower the try to shake the remaining product the length of the bottle to squirt it out. This takes much more time that you'll want it to take. Redesign the bottle with a flat top...please.
Example Output: 2

Example Input: This stuff tastes awesome! And for once in a kiwi/berry drink you can taste the kiwi, I'd be very hard pressed to tell the difference between this and a traditional soda. I also like the fact that it's in a tall and slender can, fits in the fridge better and you can't mistake it for that pesky regular soda... :) However I would not say that this would be a better alternative to soda based on the fact that it still has a solid 33g of sugar. Yes it is better for you because it is made with 100% real juice instead of corn syrup, which I definitely like, but it's no different then drinking the 100% frozen juice from concentrate. Overall I really like the product and will probably buy some to have as an alternative to soda (for those few times a year). Pros: You can actually taste the kiwi and the berries. 100% REAL juice, no artificial flavoring. Very carbonated, not the least bit flat. Quenches your thirst and is refreshing. NO CORN SYRUP!!! Cons: Spendy. Although it is all natural, still contains 33g of sugar... 135 calories a can (ouch!).
