These were a gift, but they seem sturdy enough to be effective. Got them for a larger bike as it's a bit difficult to find quality ones for larger bikes without spending a lot. Like that it has the structural support on the angled edge. Only thing that worries me is the fact that you have to use the highest notch for larger bikes, and I am not sure if that is going to effect the chances of the bracket bending.
