Got this a week ago from my local cell store, and i have to say, i am thoroughly impressed. It was very easy to pair with my Nextel i580. I love the fact that, unlike most bluetooth headsets, i can still hear my custom ringtones. All features (ie: call, answer/end, re-dial, etc) are activated with the use of one, multifunction button. The headset rests very comfortably around and in the ear. i am an EMT in the Harrisburg Area, and am very active with my job, and it has not fallen off of my ear once. Battery life is pretty good - one charge will last me my full 16 hour shift. The only downsides to this headset is the range - more than 10 feet away from your phone, and it drops your call. Other than that, this is an ideal headset at a very good price - highly recommended!!!
