Just received it yesterday. Love that it announces who's calling (if they are in your contacts already). Love that you can choose to answer the call by using your voice, in the event that your hands are 'occupied'. Holds a charge all day, even with heavy use. I know it's only been a day, but I think I'm going to really love this unit.....wish I wouldn't have waited so long to replace my old Plantronics Voyager Bluetooth with this one. It's a beautiful upgrade!
