I do the job as advertised, but it's just rounded U-bars that attach to the monitor's vertical bar with screws. The screws are not tightened enough to ensure a secure connection. There's a nice plate that attaches to the U-bars and a VESA compatible plate. It relies on gravity to sit in the U-shaped bars. Adjusting the monitor stands allowed me to get it working in a way that served the intended purpose.
