We use Blue Ant and really love it. I stopped using the on board intercom of the Interstate because we can use the Blue Ant on any of our rides. We rented a new SoftTail while on vacation earlier this spring and we had an interphone just like on one of our own motors.
It also lets us communicate when I am gassing up and Karen goes in to pay.
We get some strange looks, but then again that's normal for us.

Well NUTS! I just looked on the Blue Ant website to find you a link to the product and it was not there. I called the tech support and was told the product was discontinued. All they make now is cell phone ear pieces.
