I have 3 motorola bluetooth headpieces and they are all garbage.  California law for 2008 requires drivers to use an earpiece.  I took one last leap of faith in the bluetooth technology, and bought this earpiece.  It got here quick, was a good deal, and it works twice as good as the motorola ones.  Battery life is amazing, and it looks sharper than any other ones as well.  I am a happy customer.
