From watching other videos on ar500 steel plates they seem extremely durable, and outlast all the other kinds in terms of longevity. The entire plate is also ballistics rated, as other kinds if hit at the edge can fail. Only two things I see as downsides are weight and spalling. Weight I can work with, and if coated right spalling shouldn't be an issue, and if you've got a decent carrier it should help prevent some of it from escaping as well. These plates look to be an inch thick?
