This does just what I want it to do. The sound is clear. I have two 12v sockets in the centre console of my car so one is used for the bluetooth plug and the other is used for the phone charger and everything is tucked away nicely. This would get five stars if you were able to plug a usb charging cable into it to charge your phone at the same time. I trust Griffin as a product and have one of the headphone bluettooth adaptors too. I suppose you can get cheaper products of Ebay etc but you get what you pay for.
Service as ever from Mobilefun is quick and hassle free.
