I've been using this product for a few months now with my Nokia 6620 and mostly in the car. I bought it upon reading the good reviews about it and I agree with them. As opposed to the one I had before, I can hear people clearly and mostly people can hear me clearly as well. It connects to my phone automatically, which is convenient. Easy to charge and it lasts long. I just wish the speaker portion could come closer to my mouth so people could hear me more clearly and I wouldn't have to talk loudly at times.
