I wasn't quite sure what to expect from products in this category, but it seems I picked a good one. My car, whilst being in great condition and not worth thinking about replacing, doesn't have Bluetooth audio capability (phone calls only), so I had been using an audio cable to stream music from my phone. What a pain that was!
Just opening the box was a great surprise - the device is TINY! I know they tried to show this in the pictures, but it really was surprisingly small. It seems well manufactured and designed as well.
As for functionality - well, the sound quality is better through it sitting in the center storage container right next to the audio in-line (BMW E90 sedan has the input there). Out of site, but not out of mind. It connects to the phone (Galaxy Note 9) every time without having to repair.
My experience has had me consider TaoTronics for other devices when I may need them.
