Query: false advertisement

One of the most horrible products I ever bought. Not only is the sound quality lower then the quality of AM radio(seriously, and I have used other FM transmitters which sound much better), but it does not do what it was advertised to do. They say that it will search for the cleanest signal, which actually convinced me to buy it because I thought that would be awsome. But it does not do this at all. It is not mentioned in the directions on how to search, and there is no button. This product should be recalled as soon as possible. It is sad that a good company like Maxell allowed such a product to be released.
