When I got my Razor, I decided to get the H3. I had a 850 with my V557, which I didn't like much, the phone or headset. I love the razor & have had no problems other's have described. If you put it on the right ear, the right way, it stays much better than others I've tried. It is clear as a bell & as far as the echo goes, if you turn the volume down on the headset, wala, the echo goes bye bye. All in all, I'm very pleased with it. My only complaint is that I don't seem to be getting the talk & stanby time described by Motorola or the person I got it from on e-bay. For the money, you can't beat it!! It cost me 1/3 of the price of the hs850 when they first came out. Always wait a while when a new product comes out-best advice I can give you.
