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 Drew Gengler

Excellent sound quality for music. Excellent connection. My audio input is in the glove box so I was concerned that it would be covered up there, but that doesn't affect the connection in any way. Pretty bad microphone for calls. I can hear the caller perfectly but he complains about the loud car/radio audio. Nowadays it is far inferior in quality to most car microphones. I open the glove box for calls and it still sounds bad. Another complaint is that I have to press a button every time I want to connect. I would prefer if I could just connect using my phone's bluetooth menu. But he does his job. Actually I only wanted to use it for music and once connected it fulfills my expectations.
