I used to have a traspod...which is an expensive transmitter (paid nearly $100 for it) which used to work great, up until it broke as I was removing it. I decided to shop for a new one online, and when I came across this product I didn't believe it would be as good since it was being sold so cheap! I was so glad when I received it because not only does it play clear sound but I can use it without removing my iSkin. I have the ipod mini and with my old transmitter you would have to fit it inside and i always had to remove my iSkin (which became a nuisance since I would use my ipod inside and outside my car)...but with this product there is no need. Highly recommend it!
