THIS THING IS THE BEST!
Got it a couple weeks ago because the AUX input on my work truck has a short in it… I didn’t realize that this was freaking BLUETOOTH for the input! Yeah, I know, I could have read and learned that.
Anywho, if you wish you had bluetooth audio, buy this. The FM signal is quite strong and really impressed me from my knowledge of when I actually used FM Transmitters on a daily basis. The device has 2 usb charging ports and 1 is 2.1A which is great, but I love the ability to plug in my own 3A USB-C car charger.
TLDR - if you don’t have bluetooth phone/audio in your car, but do have an FM radio, buy this.
