As a California Resident I needed a blue tooth set up, after checking out online as well as other reviews I chose this product because of the style and quality of sound. I have used the other style, like the rectangular shape it felt like it was falling off or loose. This one is perfect. I would totally recommend this piece. It is nice because you can fold up the mouth part while not in use and keep it on your ear with less view to public... I don't like to look like I am so important that I need a phone on my ear constantly. With the laws in place now, I suggest you get this one.
