Very sturdy but also very heavy. Wide base plate sits steadily on grooming table without rocking. Folding arm mechanism is smooth. The 2" dial knobs are easy to operate (important for anyone with a thumb issue coming on!) and secure without trouble. Adjustments possible both at the table level and higher on the arm. The knob off the side is useful for adjustments AND for holding your suit bag at the dog show. The grooming loop was wider than I would have selected, but functional.
