Q: What a junk. Every time NOMAD thinks the file is corrupt the OS freezes. The only way to recover is to plug the power cord and go into recovery mode. So if you happen to be out of the house and you have a frozen OS you can't use NOMAD until you get home. After OS froze twice on me in the subway I returned the jukebox.

A: Negative

Q: Ordered two and tested them out: one had a bad pump but the return was easy.These airbeds are super cheap and great. Everyone who has slept on them says they are extremely comfortable. They hold the air well. I recommend them very highly

A: Positive

Q: I don't know if you can actually call this music. It is truly terrible. However, I love listening to it for some strange music. ... I am not normally a fan of rap music, but I laugh out loud every time I hear some of these songs. These Cash Money guys should be comedians. Except for Juvenile, since I can't understand anything he says, which is also rather funny. Don't buy it for the music, but it for the comedy.

A:
Positive
