Using this Phaser3D Apex EVO 20° DJI Action 2 mount is easy. First, attach it to your ImpulseRC Apex EVO. Then, mount your DJI Action 2 securely on the mount. When using the ND filter, insert it into the single ND Filter slot. If you have an acrylic screen protector, place it in the Screen Protector Slot. As for maintenance, keep it away from sharp objects to avoid scratches. Clean it with a soft, dry cloth regularly. Remember, the frame and other parts shown in the picture are not included, so don't expect to get them with the mount. Also, if you want a carbon fibre panel, stay tuned as it will be available soon.
