This is a great Bluetooth head set. It has a long standby and talk battery life, longer than the old Plantronic head set I had. I particularly like the mute feature for those long conference calls while I am on the road.The one draw back is it is heavier than other Bluetooth headsets that I have tried in the past. This makes it harder to have on your ear for long periods. The plus side is you will no "forget" its on your ear and take if off so you don't look like a geek in public places.
