After reading some of the on-line reviews which I located thru Google, I had "Great Expectations" for the Logitech Mobile Bluetooth coupled with my LG 325 phone.I have to say, when in-doors, beit in the house or in the car with the windows up, it works wonderfully!BUT, take the unit out of doors and the fabled "Windstop" microphone fails dismally. AND, what good is a wireless headset if you can only use it in-doors????
