Review on Calling Adapter Bluetooth Transmitter Compatible by David Miller

Pros Display size and brightness are good Both charging ports work fine. The gooseneck is quite long and flexible. Supports most audio formats. The FM transmitter is quite powerful (haven't had any transmitter interference so far) Tested with 64GB of memory, everything is fine Cons The buttons are not ergonomic (to change the mode or setting it is better to do it with a complete stop the car or may have an accident) No automatic search for channels (you have to find a free frequency yourself) The player/compiler is quite slow (when you select a file or folder, don't expect it to play it immediately, depending on audio format it may even take up to 15 seconds to start playback ). Talk while driving, expect the listener to complain and ask you to speak up, it really depends on the charger location)
