I received mine on Friday and am very impressed with the build quality. It is very heavy gauge steel and the welds are strong. The finish is perfect and it looked great fully assembled.

I did have one problem, the table I am using for a desk has an awkward side rail and the clamp was not able to secure to the table. Since this is a temporary office, I will make sure my new desk can handle a clamp-on stand like this. My issues aside, the clamp is very nice. It uses two heavy screw clamps and is adjustable up to 6"+

I just had to see it work, so I took my monitors to the garage and hung it off the side of my workbench. It held my dual 22"s fine and I was able to adjust it in all the ways I expected (left/right and tilt) to the configuration I wanted (one landscape the other portrait, concave to each other, perpendicular to my desk)

Be warned, that the arm is one piece, so you cannot offset the heights. If you want your monitor centers to be at different heights, this is not the product for you.

Conclusion: for us cheap bastards, this thing is awesome!!! I will definitely buy from this manufacturer again.
