In regards to the above, please be advised that the above bluetooth 1. not new. 2. can barley hear the caller at the highest valume. 3. there was a double order for the above , which I called customer service and advised them that I was billed 2 times for the bluetooth and was told to refuse the second delivery and I would receive the credit for it as of today May 29,2009 no credit whice has been over 2 weeks I have send your customer service an e-mail to this effect with no response. That left a bad taste in regards to amazon.
