The silver speed ring is made of a rough material that will definitely hurt your hand when you use it to assemble light modifiers. The black mount is flimsy and should not be used with anything larger than 24" x 24" lightweight mods or larger lightweight mods. The point where the vertical bar meets the bracket is a small point of contact that will bend under any weight or break if you take a large modifier. On the good side, it's easy to assemble and use.
