These are heavier than I expected, but that is good.  They are sturdy and deploy easily, my only minor gripe is that the legs have to be bent back somewhat before they will unfold.  If you were to unfold them without bending them first, they are going to break.  This wasn't a problem when I tried them at home in good light, but I could see if my first attempt was by the side of the road in the dark the legs would break off.
