Ex Input:
Bought a refurbished one with the expectation of being able to use it straight away and save my money. Got it, plugged it in, no big deal. But that's when I found out that this is actually not made for windows 7 pro. The disc that comes with it will install on the newest computer and doesn't instal right on xp. When you try installing it runs fine but then has the annoying clicking sound which gets really annoying if you're chatting online or playing around a game.

Ex Output:
Bad review


Ex Input:
The idea of an individual book on my favorite tv show was really exciting! So when the calendar arrived it came in a timely fashion, and though there is nothing wrong with it, I did anticipate that there would be more than one episode in each month.

Ex Output:
Good Review
