Bluetooth Communicators

Does anyone use  Bike-to Bike Intercom system? I have been thinking about this for a while and reckon it would be a good thing to be able to talk to your biking buddies on a ride ("I need a leak" "Fancy a Bacon Sandwich?" "Watch out for that idiot" etc)
There are the chinese cheapo ones (BT and Buyee) but I reckon you pay for what you get. The UClear sysetem looks good as there is no boom microphne, alternatives include the Interphone F4 and the Sena models. Anyone got any of them?

Hi Grob,  I've got the Cardo Scala rider to pillion and it works fine, decent battery life,clear sound and hooks up to my phone, sat nav and music player fault free, can't read text messages through my tom tom though? which is something I like to do whilst riding  I've not tried the bike to bike ones so can't give an opinion? the rider to pillion only works to about 20 metre's, when I was looking for an intercom the Sena always got the best reviews but was out of my budget.

Cheers Sim, still reseaching but I think the uClear is coming out favourite.
