Query: BT T305

I purchased this to use in my vehicle so I wouldnt have to use a head set or worse hold the phone while driving. I was impressed that it works as well as it does. I have had no problems with this device. I am able to charge it the car if I have to and charge well at home. You can use the same USB power cord as for your phone (if its a MOTO RAZR model NOT the new V9). I take this for short trips in town. Sadly to say it will be used as a Back up due to being replaced by the MOTOROKR T505. If you are leary about trying this...JUST DO IT. If you dont like it Amazon will take it back. For a first purchase you cant go wrong.
