We are using the Chatterbox XBi2hplus installed on HJC-IS-BT helmets when riding double. This helmet has a special recess on the side for the control unit. They work pretty well. Groups of other riders can be linked in. As with any of them, they require battery charging and above all reading the directions. They are also linked to your phone if you like which is handy. Not that I ever answer the phone, but at least I know someone has sent me a text or called and I can stop whenever to answer them.
