Ex Input:
I admit that I fully expected to dislike this product, and approached it with a dismissive attitude - something that's this trendy can't be any good, right? well, I was wrong. The ONE coconut water is refreshing, delicious, and just barely sweet. Really wonderful stuff. The hint of pineapple adds a little bit of acidity that enhances the basic taste of the water. i bet this would make a great summer drink too, but I only had one so I didn't get tot try that. My problem now is that it's been out of stock, so I can't get more.

Ex Input:
If this was called "Medium Roast", I would give it 4 stars. It's a good coffee.  But this is called French Vanilla Caramel, and this review is based on the product's name.  Let me say that vanilla and caramel are perhaps my favorite flavors... coffee, ice cream, candy, you name it... if it's vanilla or caramel, I love it.  With the exception of this.  Where's the vanilla? Where's the caramel? And don't get me wrong: I'm not trying to say that the flavors are too mild. I'm saying that they are NON-EXISTENT. And therefore, based on the name, this coffee gets 1 star.
