Cover super well designed, everything is well thought out and efficient: Powerful magnetic fermerture, bottom slot to help quickly remove the unit by lifting it with the finger, rigid properly (too much or too little), fastener tab secured by a tongue back pressure ... My camera is calibrated and do not bother me even in horseback riding! Perfect! The only improvement to be made: black design is very classy, but very masculine. Think ladies and youth with more designs "fantasy".
