Hi, KoDude. It would be impossible to say that a cure (or activation for that matter) is 100% effective. Marie generally recommends that you do not sleep or work in a disaster star, cured or uncured. If it is a yearly disaster star and your period stars are good she says you may stay there most of the year but avoid the room when the negative monthly stars fly in.
6-rod metal wind chimes are the only moving metal cure Marie recommends. If you need the same cure in the same area you can use just one but make it a large one.
