The Navi is easy to attach to the holder and is good to rotate and swivel, it sits securely in place and you do not fear it might fall off. Nevertheless, the removal of Navis spreading any trouble. All in all a good product. Disadvantage: The holder snaps difficulties with the recommended "adapter plate male 4-talon locking system Screw Adapter" field. I hope to adapt the two parts with the time together.
