The band's image has been the subject of much criticism and controversy, with critics generally accusing it of being a sales gimmick. The band's members object to these claims; according to them the masks are used to divert attention from themselves and put it on the music. Several band members have said wearing the masks helps to maintain privacy in their personal lives. During an interview in 2005, percussionist Fehn said the masks were a "blessing" because they meant the members are not recognized in public.
