I found for me at least when I tried the Jupiter Jack it didn?t work very well. I had trouble getting calls to connect, and when I did get them to connect it was a constant struggle for me to hear what the caller was saying to me. This could be worse since I am from a larger area and I seemed to be fighting constant static over the radio. However, the caller could hear me just fine. So I believe the issue was with the FM transmitter and I honestly didn?t really expect much since the product is really inexpensive. So for me, it wasn?t a good deal and too much of a hassle and made it very unpleasant trying to talk to people.
