Does exactly what I need it to

The radio transmitter is great. It is easy to use and makes playing music in my car very easy. I have had no problems with i. Worked exactly like it was supposed to right out of the box and I would recommend it to anyone.

I have used FM transmitters before but they had to be plugged in. I thought this one would be nice to run off battery. works but kind of staticy even when its plugged in.
