Review on ErGear Gas Spring Arm Wall Mount for 17 to 32 Inch Screens - Height Adjustable and Extended Up to 18.3 Inch - Fits Multiple VESA Mounting Sizes by Mike Kimball

I really like this monitor mount, but the tilt mechanism has a design flaw that causes the monitor to slowly tilt forward over time. When I tighten the screw on the tilt mechanism, the monitor slowly tilts forward over time or with each adjustment of the lever. Each side of the tilt mechanism has plastic and metal washers. Removing the plastic disc from one side of the mechanism solved the problem. If that doesn't work I will replace the washer with a lock washer. This keeps the monitor from tilting once tightened, but in my case there's no reason for me to regularly adjust the tilt once I've set it up the way I need it.
