I don't get it...a friend of mine has one so I got it thinking it worked well. I get and first, it doesn't fit my ear. In fact it doesn't fit anyone's ear so everytime I turn my head in the car, it flies off. Great for safe driving huh? Then, everyone one I talk to says they hear an echo of themselves when I use it. My friend who has it, tells me he has the same problems. I should have asked him how he lked it before I bought it. This is the worst money I've spent in a very long time. I hope this review helps others not to buy a bad product!
