it works with LG VX8600, but not with Motorola V3M from Verizon. At first my LG vx8600 is having hard time finding this device, but once it creates the profile, connect is pretty easy. If the volumn is loud, it has too much feedback for the other end. so the volumn has to be small, kinda bad for driving with a lot of road noise. charger and box quality feel quite cheap. THis is my first Bluetooth headset, so I don't know how it perform compare to others. it is a mediocore performer in my opinion.
