They're definitely great for holding heavy objects and I find their weight capacity is definitely spot on. The technology is amazing and the crack you hear as the screw turns is oddly satisfying. My problem with this product is that the plastic screws often break. You have to hammer them in and once screwed in (to the start of the screw) you can just drill them into the drywall. I cracked about 3 out of 6 of them before pre-drilling a half inch hole to prevent them from snapping before screwing them in. Another downside is that the plastic Phillips screw kept breaking off when trying to remove it. You must use a wrench to remove these screws if you want to shine and attach to your wall. It's a tedious task, and the hole it leaves is definitely daunting. You have to use your hands and tear off some paper in the drywall to repaint it perfectly.
