Query: Great... while it lasted.

This product lasted for a little over a year before I started to notice malfunctions. The power button and other function buttons such as "Source" and "Volume + and -" stopped working soon afterwards. Despite the advertisement, it was actually unable to fit ipods and iphones snuggly without the purchase of (separate) docks. Very disappointing for the amount of money that was invested in this product. Warrantee only covered for one year. What a waste of $!
