Query: Great sound, high quality product.

The sound quality is GREAT, and it's portable with 8 C batteries. I recommend buying rechargeable batteries (http://www.walmart.com/catalog/product.do?product_id=10242693) so you can take it on the road and not fret about burning out the batteries.Note of caution: Much like seemingly any ipod dock, I experienced a connection issue after a summer of RUGGED use. I'd have to put something behind the ipod and lean it forward in the dock before it'd work -- again, I've seen this issue occur with many different models. Returning it to Creative (Cambridge Soundworks sells the product, but Creative Labs makes it) is a hassle, but they'll come through for you in the end and send you a replacement. They've laid off a majority of their customer service employees to stay afloat, leaving them with 7 TOTAL at last check. Because of this, the phone number is nearly impossible to find. If you need to return the product under warranty, call 1-800-469-9269.
