I have had three previous older models of this bluetooth and the only problem has been misplacing them. I wish I had never purchased these two. One never charged at all and the other worked for a while only now it has "noise" in it.I do not know if this product was a factory second, or reject but I am very put out and will NEVER buy another item from this vendor. To return the faulty bluetooths would be difficult for me as I am currently recovering from total hip replacement and am still recovering. I will not recommend this vendor as the return policy is a pain.Thank you for allowing me to vent.Sarah Beth De Ment
