Query: Not So Much

Sounds good, but as others have pointed out, the controls are hit or miss. Sometimes the thing will just decide to turn down the volume. And if you accidently hit the shuffle button you have to take the iPod out and manually scroll to unshuffle. Also, my iPod gets really hot in the craddle and I'm not so sure that's a good thing. I could go on, but suffice to say DON'T BUY IT. Too many problems.
