I bought this thinking I could use it in the car while driving. First of all, since the microphone is attached to your ear, other people hear all sorts of noise besides your voice; Second, I can't seem to pick up incoming calls and seem to have to answer it with my cell phone which is what I wanted to avoid; Third, can't tell when it's running out of juice since there is no indicator; and lastly, it disconnects from the cell when it feels like it. I would wait for technology to get better before buying this kind of thing.
