Review on 🚗 Beinhome FM Transmitter Car Kit with 3.5mm Aux Port - Wireless Audio Adapter for Car iPhone, iPod, iPad, MP3 Players & More! by Leonard Babers

Not a bad unit. I listen to a lot of music and use the FM transmitter to send music to the radio even when I'm not at home. I noticed a strange thing that happens when there is no input signal, the device turns itself on, thereby saving batteries. This can happen when your MP3 music is running low and you have no other choice in the queue. I keep mine plugged into a USB port. A lot of people say the audio jack doesn't fit their phones, I just bought a few inch extension cord. Yes, you spend more money, but I don't mind. A few things I would like to point out: There are no instructions, nothing but a folded piece of paper from the seller asking everyone to contact him for anything. They also mentioned sending a guarantee but not where to send them and there is no serial number to report. Maybe they wanted to use their email address.
