Not the strongest material you will ever find - make sure not to overload it. They look amazing and I wanted them because I wanted the wall supports to be above the shelf and not below. I keep all my weight on the back of the shelf next to the wall and increase the strength of the anchors a bit (better than the ones that came with the kit. Still on the wall for now haha. But they have quite a bit) in them, and they are "more flexible" than I would like. I've used them on two different projects, one for a shoe rack and one for kitchen shelves. A shoe rack is definitely better suited for this, as shoes are of course much lighter.
