This is one of the worst books I've ever looked at and read. It's just a waste of time. Save yourself 4 days with your friend (who isn't reading as well), read something, anything! You will actually learn more watching paint dry. In all seriousness.

Ex Output:
Bad review


Ex Input:
I purchased this little converter for my Samsung 3D TV. It works great. The best part is that unlike other converters in it's price range - I can now receive all of the TV channels without having to hook up an extra antenna which was costing me $80/month before.

Ex Output:
Good Review


Ex Input:
We have purchased this model before and wanted another one so we can listen to music from iTunes (iTunes) on the home theatre PC using our Bose radio speaker set. We could not get a decent sound quality with this unit, very disappointing considering all of the other great reviews. I suggest you look elsewhere for similar products.

Ex Output:

Bad review
