This inexpensive product doesn't seem like it would perform too well but i've tried several brands of bluetooth headsets and this one is by far the best.  The price is excellent for such a high quality bluetooth headset.  I bought it for my father and he is not very techy but he finds it easy to use.  Once I set it up for him (which was a piece of cake) he's been able to use it without problems.  The range is excellent and you can leave the phone downstairs and go all over the house and still have a clear signal.  No bluetooth headset will ever sound as good as talking on the phone itself but this one comes very very close.  The sound is crystal clear and there is no static or echo sound like some other brands have.  You can talk for several hours without killing the headsets battery.  I would highly recommend this inexpensive, light weight, fast charging headset to anyone.
