Review on 📻 GUANDA TECHNOLOGIES CO., LTD. Bluetooth FM Transmitter In-Car Wireless Radio Adapter Kit with 1.8" Color Display, Handsfree Call, AUX In/Out, SD/TF Card, USB Charger QC3.0 - Compatible with All Smartphones and Audio Players by Dre Fowler

This is an amazing device! Durable and easy to use. Looks good and works great. Amazing connectivity and great sound quality. Although the user manual is not very detailed, I was able to quickly learn how to use the device (it's quite simple) and was very satisfied with the result. Initially I was afraid of connection problems as I couldn't find a completely "clean" radio station to set up Bluetooth. Do not worry about it. Bluetooth completely suppresses the weak station. (Maybe even strong, ha.) I set it to 107.3 fm and it plays absolutely clear wherever I ride! Never hear interference. I've used it with both the aux input and the USB stick and both are fine.
