How to use

Open the adjustable clamp and place the smartphone between the jaws, then tighten the clamp until the phone is held securely without excessive force on the device.

Rotate the phone within the holder to switch between portrait and landscape orientations as needed. Make small adjustments to the clamp and joint to maintain stable framing during recording or calls.

Usage recommendations

Ensure the smartphone is centered in the clamp and the clamp is tightened sufficiently to prevent slipping. When using heavier phones or phones with protective cases, verify that the clamp holds the device securely and avoid over-tightening. Use the adjustable joint to fine-tune the angle and lock the position before starting recording or streaming to reduce vibrations and maintain consistent framing.
