I bought two of these. Good bang for the buck. Used for some carpentry work to hold trim pieces in place while the glue dries. Pretty good overall quality, solid/strong downforce, little forward/backward tension/movement of parts when clamp is off-center. I'm glad they are plastic/rubber composite with steel springs rather than solid steel, should have fewer rust issues and should last longer. Composite feels like glass fiber reinforced nylon, nice and tough.
