Ex Input:
The pineapple coconut combination is refreshing. I especially like that there is no added sugar. This is a welcomed change from other brands.

Ex Output:

Ex 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.

Ex Output:
2


Ex Input:
The batter seems to require more moisture than the instructions call for and they don't give a baking time, but 4 minutes seems to work about right. The waffles taste more like regular waffles than Belgian Waffles. I was hoping they would have a more "malty" flavor.
