nklr intercom & 2-way communications

[Dust]

Is there anyone out there using an intercom for 2up riding? Maybe some rider to rider communication device? I am considering using the chatterbox system, but will not be ready to purchase for a few months. I have read the info on the net for several types, but want "real world" experiences and reviews. Any assistance will be appreciated. Thanks in advance, Dust A14 Man with Big Grin
