Example Input: I've now been through three of these cords. they seem to last around a year before just dying. The first two eventually had fatal connection issues with the piece that connects to the computer, however my third one has just died and is actually not getting any power from the wall. The little indicator just fades out, and now won't come on at all. Yes it's a lot cheaper than the other cords, but I'm just not sure its better. I know lots of people have problems with the apple cords as well.
Example Output: Negative

Example Input: It is extremely rare to see so many world famous super artists performing together in the same concert doing some of their greatest hits - Elton John, Sting, Mark Knofler, Carl Perkin, Eric Clapton, Paul McCartney, Phil Colins etc. You must own this DVD before it is out of stock. I would have given it 5 stars should the audio recording be slightly better. Go and buy this one with confidence. I am sure you will not regret.
Example Output: Positive

Example Input: Even Cage, with some genius acting in parts, couldn't save this bad movie.One of the wosre movies I have ever watched.Why do they keep hiring Eva Mendes - she acts like a piece of wood.
