The Scala TeamSet Rider is a minimal comms unit for intercom and BT connectivity, with a cell phone. I cant give a blaring endorsement to neither the cell phone connectivity nor the intercom. Marginal at best and as for comment on material and workmanship, I am quite disappointed with the sturdiness of the boom mike connection with the base module that is mounted to the helmet. One of the two in the set is now useless, T.U., toast, broke, POS...useless. It surely isn't military grade.
