I am a very sporadic bluetooth user, and mainly bought this device for use on long car trips or when I don't feel like holding the phone to my ear. This device goes well beyond all of my technical requirements (great sound transmission on both ends, vibrate alert, pairs well with the LG Chocolate phone), but my only complaint is the fit of the earpiece around my ear. I am a woman, and the earpiece feels VERY loose on my ear when I am wearing it. In fact, when I'm in the car and need to check my blind spots, it has fallen off many times. It is not easy to put onto my ear, so if I need to take calls when I am driving I need to keep the device on my ear for the entire trip. Perhaps I have misshapen ears, but in my opinion a headset should fit a bit more snug to be comfortable. I would suggest trying one before buying one!
