Review on AGPtek Upgraded Portable Car Aux Bluetooth Adapter & Receiver for Mp3 Music Streaming Sound Speaker System, Hands-free Audio Adapter, Bluetooth Car Kits with 3.5mm Wireless Aux Jack by Robert Tyus

Bought today to get rid of the audio cable from the phone to the aux input. Fits perfectly in my glove box where the side entrance is, very small profile. Charge it up, plug it in, and be amazed at how much better it sounds than the aux cable plug. Much more power than the aux cable setup I used (wireless output equivalent) and crystal clear sound. I'm giving 4 stars at the moment because I can't confirm how long the battery lasts when new and over time.
