Bike to bike intercom?

[stevierst]

I'm looking at buying a bike to bike comms device and currently doing a bit of research on it.

I'm considering either a Bluetooth type device, or a walkie talkie type radio.

Do any of you guys use them? If so, what is it and what are the pros/cons.

I'd also like it to be used as a rider/pillion too if possible but not a priority. Its so I can hear the missus complain about my last dodgy overtake
