Best quick-release phone holder

Since my phone is now my camera, I needed an easy way to attach it to a tripod. The solution is this metal adapter that holds the phone with a circle of magnets. The Mosenvka Portable Phone Grip ($29) then screws into the tripod head. But once I had it, I started using this same rig to hold my phone on my desk for FaceTime and video sessions, at the perfect angle. Its base also has a second heavy-duty magnet so the whole thing can stick anywhere there is metal, useful for filming. The holder rotates in any direction at any angle with just the right balance of ease and stiffness, to keep the phone rock steady. The whole thing is machined metal instead of plastic, so it is very rigid and stable. If your phone supports it, a magnetic ring is by far the best quick-release hold system. — KK
