C4 was beyond shite, as was the comms system . Never again .
Had the sporty lid (S1?) from them. Failed badly, vents jammed, extreme fading of paintwork. Took the dealer & Schuberth so long to deliberate as to what to do I bought a Shoei elsewhere. Then they wouldn't process a refund, insisting it was a case of replacement only, which went straight on eBay at a loss. Would never buy another Schuberth.
