I didn't hold out much, if any, hope for these pliers, tbh. I just thought they were another marketing gimmick and would not remove the three screws that I had complete stripped the heads off, trying to get them out of my bathroom door. I couldn't have been further from the truth. They grip to even the slightest/thinnest edge of a screw and do not slip at all. I removed all three of my screws in under 5 minutes and I'm absolutely delighted to have found a solution that actually works.
