Review on Malta Dynamics Standing Seam Anchor by Guillo Tilden

It takes a while to get comfortable with such a small piece of security but it works. I knocked it over the first time and smashed the metal roof. The only thing I would like to improve is the time/force required to tighten and loosen the clamps. It would be better if it didn't require a wrench either, another thing to watch out for if this isn't ideal on a very steep roof.
