Magic Arm Upgrade Kit
"Upgrade your Universal Mount, with its pesky and guaranteed to-breakdown- eventually lever, to our Magic Arm, with the magic knob, that never needs replacing, is much safer, and instantly makes the arm infinitely easier to position! And anyone can perform the upgrade in about 5 minutes (upgrade kit consists of knob and related hardware, including necessary Allen (hex) wrench)." RJ :-)
Once you've upgraded, you will be able to *easily* adjust and control the Magic Arm. It makes a HUGE difference!
