With auto com, it's good kit but not without issues. Dodgy push to talk buttons, failed with water ingress. Me and three friends all bought the same kit new and all suffered same faults. But apart from that and varying degrees of radio interference from local taxi firms they worked pretty good.
Then I met my wife who didn't like having to plug in all the time so we decided to go blue tooth, a pair of BT midland thingy's for £99 these were good value, quite simple, no wires everywhere reasonable range and lasted a day on one charge. Problem was in a torrential down pour one packed up but we both liked the convenience so I invested in a pair Scala G4's.
these have great range one charge last for ages sometimes several days. You can update soft ware on line to keep up with the latest and switch between several users.
Although expensive they have been the best so far. I have fitted microphone and speakers to our trials and green laneing lids as well so we just clip the G4 on whatever lid we are wearing.
Deffinately Blue Tooth for us.
Good luck
