Input: Consider 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!

Output: Negative


Input: Consider Input: Do not buy this toy. If you are given this toy as a gift, return it for store credit. This is a flimsly and poorly designed stack of platic and paper. The secret door doesn't work, the elevator doesn't slide and toys get stuck in there. The suggested 10" batman doesn't work with the zip line, bungee or even the elevator. The add says "Using new adhesive technology, you can set up the Batcave on just about any wall" so they want us to glue this thing on to a wall.Please don't buy this toy.

Output: Negative


Input: Consider Input: A BRILLIANT READ!!!! Easily the most exceptional book on religion, power, and politics in Colonial St. Augustine from the Florida Museum of Natural History. I found it gripping from front page to last. The way St. Augustine came alive, it was like i was really there. This is a must buy for anyone who finds American history thrilling. Genius! Robert L. Kapitzke is one of the most well versed authors of our time.


Output: Positive
