I purchased this Bluetooth to FM transmitter about a year ago, and besides one of the lines on the display going out,(something which doesn’t really matter to me as I don’t need to see it) it has worked flawlessly for me. I am a military man, and this is a cheap little device that has worked great through my time in the desert and back home. I’ve used this in plenty of vehicles without any problems, and the music quality is basically on par with any normal radio stations.
