Review on Enhance Your Car Audio Experience with Bluetooth FM Transmitter: Wireless Radio Adapter, Hands-Free Calling, Dual USB Ports, TF Card/AUX Support by Ronald Dimatulac

I've had the Nulaxy for over a year (I've actually had to replace it twice in that time). I had my 3rd replacement in less than 2 years because it kept losing power. Then I bought 4 different others until I found this one. Sent everything back but left this one. Doesn't turn off the power, the sound is superb, it has all the frequencies I need. Only 87.9 works in my area and I was surprised that not all stations work on this band. It has. Also, some other stations might overwhelm other radio stations or transmitters nearby, and you might get a lot of interference just driving down the road. I don't have a problem with that. Overall, this is absolutely the BEST Bluetooth transmitter I've ever owned.
