Review on 🚗 Criacr (Upgraded Version) Bluetooth FM Transmitter for Car: Dual USB Charging, HI-FI Stereo Sound & Hands-Free Calling - Compatible with All Smartphones by Niko Knight

I've finally found a working transmitter that's easier to use than anything I've bought before. You can charge TWO devices at the same time and thanks to Bluetooth you get rid of the auxiliary cable for audio. It is perfect for new iPhones. I have an iPhone 5S and it works great. Find a station that isn't being used and doesn't interfere with other stations. Through trial and error you will find out what works and it is easy to do. I transfer it from one car to another. My son has one too so I bought one.
