Recently some buyers ask us about the new security mechanism of the Benro ball heads (specifically B, V and G series)… “Hey, I can’t release the QR plate from the ball head, the knob stopped loosening at halfway with only click sounds! Is it malfunctioning? Or is there any trick to make it open?”
Certainly it’s not malfunctioning. It’s actually the new Security Lock Design of the Benro ball heads, which was designed to prevent accidental dropping of the mounted equipment.
