This was the biggest waste of money ever created. If you want to know the song that much, call the station and ask them, they don't mind, really.

Ex Output:
Negative


Ex Input:
It does an excellent job on mildewed wood such as decks and deck furniture without using chemical mode which is the only weak link in an otherwise strong chain. Unfortunately, the only effective chemical solution is chlorine which acts more or less on its own but cannot be used with this machine. Safe cleaners, such as Simple Green are no more effective than when used without them. Other than that, it's a great product.

Ex Output:
Positive


Ex Input:
This book should have been written more as a novel than a how to. This book goes into story like dimensions and there are others better written on the subject.

Ex Output:

Negative
