Comments about Bogen Imaging Bogen - Manfrotto Variable Friction Magic Arm w/3299 Quick Release (#2929QR):

This arm is really magical. Being able to loosen all the pivot points at once and then lock the arm into a position with a single action is awesome. The variable resistance arm is simple and easy to use. Also, pay attention to the tension of the arm segment bolts. The kit includes two allen wrenches. If the arms are too loose, disengaging the level makes the arm segments drop down quickly, potentially harming equipment. Make sure the tension is tight but still flexible. This tension setting levels varies out of the box as I've noted by testing three units.
