It works great but my husband had to use his own larger drywall anchors instead of the ones that came with the dowel strip. We didn't have hairpins here. The anchors they gave (little blue anchors) couldn't support the weight of the pen strip. He noticed that he already had the same size screws in the drywall anchor pack, but they mated with much larger anchors, so he tried these out. After that he got up normally and remembered everything! I would buy again.
