Review on JETech Wireless FM Transmitter Car Kit for Smart Phones with 3.5mm Audio Plug and Car Charger - Rose, Reviews & More! by David Hayden

I was happy to get something that would play Spotify, Pandora etc through my car speakers but this unit let me down. Unless I'm in the middle of a big city there's so much noise that I can't even use it most of the time, and when I use it there's almost always some level of noise, and yes I've tried Setting the frequency does not work. Eventually audio only plays through half of my speakers and then nothing plays. The seller replaced the product for free, but the second one does the same after a few months and stops working. The device is not designed to last. I do not recommend this.
