It takes almost the strength of Hercules and a shot of steroids to loosen the pivot adjustment on the arm. I can do it, but wife and kids (not that many). It's pretty easy to install, really solid and heavy enough to carry my 55 inch flat screen outdoors. I like the ability to rotate the arm (with the Hulk's abilities) 90 degrees. The price is very good but I wish these adjustments were easier. .Maybe I'll buy again if necessary.Maybe I twisted at the Chinese factory?
