I would look at me as a good craftsman, have built several houses! But this rod has forced to abandon me. The bar is not suitable for plasterboard walls, as the anchors of any halt missing. Also use with drywall anchors is not possible because the screws are so wrong that it can not be easy to rob. Profit after two hours of work was two large holes in the plasterboard and a stake in the garbage!
So if the bar for a plasterboard wall needs, stay away! For other walls, I have doubts about whether the bar could be worth their money!
