I have had two of these now and initially they worked fine. The reason for the second though was that the first one failed and I was not able to find replacement parts anywhere on the web. The second unit has now failed and this time i don't feel it's worth replacing anymore parts, not that it's easy to tell which part has failed. While the dock is working it is fantastic though have to agree with on of the other users as the parts do not feel very well made. Sadly I am now looking for another dock for my ipod that is fitted and does not rely on an FM transmitter.
