Review on Upgrade Your Ride With Criacr Bluetooth FM Transmitter: Dual USB Charging, Hands-Free Calling & MP3 Music Player by Brian Douglas

Works very well!Do not believe the one-star reviews. This works very well. Pairs ever time. No static at all. Turn up your media volume on your phone to full or one notch below full. Sound quality is excellent!Getting phone calls while listening to music is easy. You will have to speak louder and direct your voice towards this device. The caller may report voice volume seems low. That is very typical with these devices.The only thing I don't like is the "waiting for pairing " British voice everytime you start the car. It can be very loud if you don't turn down the volume before turning off the car.Edit: There is a little engine whine noise if you turn your car stereo's volume all the way up. It is not audible at normal volume. I am sure they all do it. Just make sure your media volume on your phone is turned all the way up. You won't hear it.
