It works like Magic. I have a Lexus RX300 that does not have Bluetooth, I wanted something that can connect to my Cell phone Bluetooth so that I can play songs and when the phone call comes I can take that call using my CAR speaker system. It works exactly what I wanted. This tiny thing is just magical. It connects right away with my cell phone Bluetooth. I don't use other features that it has but for me it works great. The only minor issue I had with this that it has plastic body. last time I took my car for car-wash and they broke my BTAXS Bluetooth but fortunately it still works. If I have to buy again I will buy this again and would recommend anyone who has old car or new car without Bluetooth hands free. This is the best product with extremely low price. ( i am not giving 5 star for Durability because i feel they can do better job by not making it completely plasticy). But again I recommended all my friends and some of them also bought it and are using it.
