It took a little while to figure out how to get the radios set up, but it's well worth it. It's not the complete radio either. It has been disassembled to slim it down and, in my helmet, it sit's flush with the padding. The only thing left to add is seperate controls on one of the gauntlets so that you don't have to remove the helmet to change channels and volume etc.
Kamakaze and I initially installed these for the cons. It's too simple and cheap not to have one.
