This is not a spotter remark, but I didn't think their livery did much in terms of advertising. Didn't quite make you turn your head and think, "hey, who are they? Must surf the net and check them out". To the untrained eye their aircraft looked more like corporate jets. I think this WAS their intention but it wasn't a good self-advertising strategy. Very sorry to see them go though. Best wishes to all DUO staff.
