Query: Does the job... However you lose significant quality!

This idea is a very good one. It works. However, there are only 4 stations that you can transmit to and those stations, depending on where you live might already have a strong signal going out on it. Where I live, in Chicago, it does an average job. However, there are more than noticeable spots of interference in the frequency. It's extremely annoying to have this thing in the car and get good sound for about 5 minutes and then all of a sudden start hearing interference. It's definitely better if you use it in the house next to a stereo system. For the car, plain and simple, it stinks. For home, it does a much better job. The Griffin made Itrip is worse than this, even though it can transmit to any frequency. So if I had to chose between the two, I probably would pick this one.
