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: We tried these chips because DR. OZ had recommended them on his show as a healthier potato chip alternative.  My whole family loves them, we have not found a flavor that we don't like.  These are WAY better than any baked style chip.  Try them and you won't be disappointed!
Example Output: 5

Example Input: So after comparing this to Jay Robb, I can say that this protein is not as good. The taste isn't as good, and it doesn't mix that easy. I don't think it is horrible, just not that good.  One thing I like about the Jay Robb is that they use hormone free chicken eggs. I sent Healty N' Fit an email asking where they get their eggs from, but they didn't reply. It is a little cheaper, but I found the Jay Robb at Vitamin Shoppe for 20 per 12ozs, which isn't bad. I have to say that I don't like the dudes picture on the bottle, but that's my only complaint.
