Review on 📦 Closetmaid 7546 12PK White Down Fasteners: Convenient Space-Saving Solution for Efficient Closet Organization by Aaron Moore

Technically they work but are still very imperfect. The shelf takes a lot of effort to "push in" at first, but then it slides out much more easily. When you use the included wall anchors, the force required to push the pole in actually begins to pull these super weak anchors off the wall. I would recommend mounting them in a stud at every opportunity. If it's not a stud, maybe buy some good anchors instead.
