In the two weeks that I've used the copy stand, it has proven to be sturdy. My only complaint is that the Manfrotto-like quick release, is incompatible with any QR system I am aware of. A Manfrotto QR plate will lock into the clamp, but does it so loosely, the camera cannot be secured to the arm of the copy stand without rattling around. My desire would be to adopt an Arca-Swiss OR system like mostf photographers have. At some point I'm going to replace Alzo's QR clamp with something better. It would also be nice to have finer controls to adjust the camera's position to bring the camera perpendicular to the table.
Overall though, I find this copy stand a much better option than others I had seen on the market, and far better than trying to use a tripod.
