There are testimonials all over the WWW. I found lots before I got a JB2. Google is your best friend as is the Search function on this site (and other BB sites). I can't offer much testimony, because I don't use a BT headset that often. It works for what I need it for when I need it. I particularly like the size and discreet nature of it. Too many of those BT headsets scream LOOK AT ME! Poseur wannabes need look elsewhere.
