Haven't been on a ship with these..so before I jump to conclusions about the mass confusion they cause (picture people getting on just because they're there with no deck buttons to push) I'd like to know if anyone has used them. Heald says "trust me you'll love them"....anyone who uses "trust me" as a phrase definitely equals "get out of Dodge" to me.
