String Swing CC01K Guitar Wall Hanger ASH

I heard these had switched to plastic mounting screws, and decided to give them a try. That turned out to be a mistake - I almost lost two guitars over it. I have a cement/plaster wall - the plastic mounting screws aren't strong enough to screw themselves into the wall, and when drilling first do a seemingly good job of staying in but in less than 30 days fell out. If the mounting screws were metal I think they would have worked out amazingly. But, String Swing decided to save some money and made the product worse. Would consider buying them again if they switched to a better mounting mechanism, but until then unless you have drywall, stay away from these at all costs.
