This is the second HS850 Motorola I have purchased, and they both work great. (The first one developed a crack in the ear loop after three years, but it's still working and I use it as a backup.) These used to sell for $99.00, so at this price it's quite a bargain now. (I bought the "bulk package"... it's exactly the same as the first one I bought three years ago!) I like the fact that it's easy to turn on and off by folding the boom. I keep it in the car for hands-free driving. The battery lasts and lasts... and it's easy to charge. You can get a car-charger, too! I like the fact that Amazon guarantees a genuine Motorola product if you buy direct from them, and it was even more of a bargain with no tax and free shipping!
