Example Input: While Jawbone make a great blue tooth ear bud, it doesn't interface with ears well. The Jabra solution doesn't work. It doesn't hold the ear bud well allowing it to fall off at the most inconvieniant times. It also hurts your ear and is difficult to insert. It's not the answer, friends.
Example Output: Negative

Example Input: After reading all the great reviews on this product on Amazon, I decided to go for this. I don't typically have good results from diet products, but I figured I'd give it a shot. I've been taking these for 3 weeks, as directed, and I might as well have been taking sugar pills for all the more this is doing for me. I felt like my appetite increased, I haven't lost any weight at all - in fact I've been fluctuating up and down 3 pounds for the past couple of weeks. I gave this two stars because I didn't feel the anxiety or sleeplessness that some people complained about, but I'm still disappointed. I was hoping I'd find something that actually worked!
Example Output: Negative

Example Input: Talk about a hokey plot and cheezy acting -- this movie is GREAT !! The 1980's will never be forgotten as a decade of some really sad movies. My God does George Clooney look young and with that mop of hair..... Can't wait to see The Killer Tomatoes take France.
Example Output:
Positive
