Review on 📻 (Upgraded New Version) V5.0 Bluetooth FM Transmitter with 7 RGB Color LED Backlit Radio, QC3.0 Dual USB Ports, Supports TF Card, USB Disk, Hands-Free Calling, Car Kit by Jonathan Arroyo

Sound quality is a big issue. You must turn the volume up fully on your phone or other device, as well as the adapter, to hear it on the radio. Also, in some areas of the city, there is too much feedback (grating sound) to hear the music. In general, everything is fine, but if you have money, just buy a new car radio with a USB port.
