Ex Input:
This was a weird drink - I had high expectations, but the flavor was just odd - it really did taste like fizzy Tang drink mix.  However, my kids really liked it, and I think it is a great alternative to junky soda, so I will most likely buy more - but not for ME to drink.  ;)

These chips are the only ones I found to be tasty and healthy. They have fewer fat calories plus higher fiber for those who want good taste and nutrition--the perfect blend!

Ex Input:
These truffles are not as great as they are made up to be. I thought for the price they would have a greater taste, but they didn't have much taste at all. They are not worth the price, but had to find out for myself. I will not be buying truffles again, and I'm not going to spend over $10 for a fresh one.
