After my fiance got her 2015 Golf that has Bluetooth built right in, I got jealous. I have an '09 Jetta with an auxiliary port that I always just had a cable run from my phone to the aux port and I never had an issue with it. Well when she got her car and I saw the beauty of a wireless connection, I needed to have one and I didn't want to spend $300 for a new in-dash receiver with Bluetooth. I found this little unit and immediately jumped on it. At the time of writing this, it costs $17 on Amazon. So $17 instead of a few hundred is a no-brainer.
It was easy to pair as you simply hold the play/pause button until the LED lights reds and blue, then find the device on your phone and you're done. The audio was incredibly clear and I couldn't personally hear a difference between this device or the wired connection I had before. The battery life is rated for 10 hours, but I leave mine plugged in all the time so it never shuts off on me.
It has a great form factor and overall I'm extraordinarily pleased with this product. For my personal needs of making my car wireless, it definitely works incredibly well.
