Example Input: I was very excited to buy this scanner and was pleased with its size and weight. However, if you have a Vista operating system, like I do, IT WILL NOT WORK! The company told me that they stopped selling this product over a year ago and there are no driver updates available for this product. If you have an older computer and an older operating system this product might work for you. But as for me it was a waste of money!
Example Output: Negative

Example Input: I am anxiously awaiting the arrival of my CD. I was at the concert in Atlanta and was mesmerized during the entire show. It was so surreal..to be in the company of Barbra and Il Divo. I know the CD will be great. It will be the first thing loaded in my car. And, it will probably stay in there for quite a while. There is and will be no other Barbra. I only wish she would tour more often.
Example Output: Positive

Example Input: There is no room for RINOs (Republicans in Name Only) in our fight to win over the general population concerning the merits of conservative principles. Horowitz's book documents the fact that rightward ideas are winning ideas and will resonate with voters across the nation. This is a collection of essays, and, for the most part, they are brilliant. Two chapters, The War Room and How to Beat the Democrats, should be very influential upon politicians and the average reader. He preaches tactics and strategies that conservatives must hear and internalize. Important points are that politics are emotional and they should always be about hope. Republicans would be wise to learn from the words of this master. Ten more Horowitz's and the country would be in a much better place. He speaks his mind in beautiful prose and you'll turn these pages quickly. This is a highly recommended choice, indeed.
