Example Input: I got this drink expecting the carbonated taste combined with kiwi and berries. Well I could taste the berries but no kiwi. I did like the carbonation with real fruit juices without the added sugar but it is not low cal. I think that I liked this drink better than the tangerine drink but still is not for me. The drink is way too sweet for me to enjoy it.
Example Output: 2

Example Input: This product smells so bad that I couldn't even try to consume it.  It smells sour and rancid and is detectable even before the package was opened.  The seller has a no return policy so I'm out the $ I spent on this as it will go right into the garbage.
Example Output: 1
