I didn't like these, but they weren't expensive either, so I wasn't too excited about it . The nails were too thin and bent too easily. I believe this will work in many situations where there is a major renovation or new build. However, I was working in a cramped attic trying to hook up my new recessed lighting. If I didn't hit the nail perfectly it would bend and become unusable, which was quite difficult in the heat, low light and tight spaces. I gave up on her quickly.
