Review on 🚗 Nulaxy Bluetooth FM Transmitter: 1.8" Display Car Charger Adapter with Hands-Free Kit, QC3.0, 5V/2.4A, USB Drive, SD Card, Aux Input & Output - KM29 Grey by Scott Kalinowski

I have both KM19 and KM29. These are great products and there aren't too many differences between them. It has a different charging port, which doesn't really do me any good. The sound quality is the same on both, which is really good for what it is. I rate my KM19 5 stars and would give it the same except for one issue I had. The device does not have the same pairing priority with my phone as the KM19. When I end a call through the device, my phone no longer plays music through the device like it does with the KM19. I actually have to unplug the device to plug it back in. That's pretty annoying and that's why I'll probably stick with KM19.
