The 'hinges' are not as adjustable and very difficult to turn as the 'screws' seem to be just for show as you can't even turn them. The middle hinge that supports the dual monitor mount is also extremely poorly made. I realized too late that the screw wasn't fully tightened; Instead, it twists together, making it impossible to fully tighten. Which, by the way, caused my $300 monitor to fall right onto my desk during installation. This resulted in some "blurry pixels/dead pixels" where my monitor had the most impact. Even when someone supported the monitor during installation, the hinge failed so quickly that my assistant instinctively jerked his arm out to avoid crushing the monitor. All in all, this is a "freestanding" mount that I bought for a thicker desk. straight up in my office doesn't work. Even when assembled, it wobbles like hell. And it couldn't support any of my 17lb monitors either.
