[EX Q]: 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 A]: Negative

[EX Q]: I didn't like some of the plot twist, of a former leader of the Autobots but other than that it was pretty good.
[EX A]: Positive

[EX Q]: This has to be the most horrible printer in the world. If I could give it -5 stars I would. I just got a new digital camera and of course just got this printer. Now when I print my photos it has blurred lines through it and is all messed up. Its print quality is horrible. It may be a bad printer - but HP is no help at all. They keep saying to install new drivers, when it is clearly a hardware problem. I want to throw this thing away, unfortunatly I got it on clearance and I'm stuck with it. Don't buy this pile of junk.
[EX A]:
Negative
