Review on Criacr Bluetooth FM Transmitter for Car: Wireless Radio Adapter with Dual USB Ports & Hands-Free Calling – Grey by Carl Movahed

So far this device has worked well. Bluetooth mic maybe a bit weak as many people can't hear me well. I write guides for work and the guides that came with this device are not complete. If you use this to connect to a radio station, the station number should flash on the device before you can tune it. If you follow the instructions provided and keep turning the knob, you will see a series of "U" numbers. The instructions don't explain what that means. It was a little frustrating but I finally figured it out. I love how much smaller it is compared to my old device.
