Technically, I have nothing to complain about on the device, audio quality and operation are acceptable. However, the wearing comfort is a disaster. The headset did not hold in the ear and drops out constantly, even with slight movements of the head (about turn for reversing or shoulder check). Then it dangles freely at the ear and one is lucky if it does not fall down. Previously I had a Nokia BH-102 and it fitted like a glove, even without earhook.
