Review on Jack N’ Drill 3-Inch Rigid Door Stop (12 Pack) - Heavy Duty Metal Door Stopper with Rigid Rubber Tip, Protects Walls & Doors - Ideal for Kitchen, Bedroom, Office, Garage by Brad Lovro

So they are well made. They are hard, beautiful and thick. I just realized that my package may have 30% defects. As you can see from the photos instead of the flat head there is an extra metal tab that prevents me from using the flat head to drill holes in the wall. Basically I had to throw away maybe half the box but if you installed it would be a hassle to return them all. You also won't know until you remove the rubber stopper on each one. Essentially, whoever is in charge of quality control screwed up the factory. It just seems like a waste of time and it's definitely a manufacturing defect. I was about to return the order and obviously it's a hassle because I already have some of these installed so I have to pull everything out.
