Review on 🔩 Inverted Drilling Anchor: Fitting Phillip by Jeffrey Sanders

Looked promising but more often than not one end of the toggle switch stuck to the body of the armature and wouldn't open. Squeezing the screw while trying to force the cup open usually only deforms the cup to the point where it breaks. It appears that slight variations in processing caused some to work correctly while others failed. If you decide to purchase, I recommend testing each cup with a screw before installing the anchor into the wall.
