Review on 📷 (2 Pack) Metal Security Camera Mount - Adjustable Indoor/Outdoor Wall/Ceiling Mount for Arlo, Arlo Pro 2 3, Arlo Ultra, CCTV Cameras - Compatible with 1/4 Screw Head by Jared Gopalan

I got them because they are way cheaper than the official Arlo. They are supplied with the necessary screws. I've used them with Arlo Pro 2 cameras and they fit perfectly. The problem I had was trying to tighten them to keep the camera in place. You tighten the top with two protruding flanges that compress the block on the ball that the camera connects to, holding it in place. I rotated it until it stopped, but the camera could still move. I rotated the mount so the ball could only move left to right, not up and down, so everything worked fine.
