The magnets hold great and are totally inconspicuous (formerly Order: Measurements note!). The adhesive pads do what they want, as long as the substrate fits. On a smooth wooden strip eg I could install it without problems. The magnets adhere but slightly more to other, more massive metallic things as the thin plates.
Tip for Raufasertapetennutzer: Forget the adhesive dots, take tacks (mine are magnetic) and sunk it in the wall. It keep the magnets just fine.
