I'm converting a camper van and had to install about 120 1/4" rivnuts. I tried homebrewing a tool but after the first few I bought this tool and I'm so glad I did. It makes it super easy to set the nuts. At least with the 1/4" nuts a single stroke of the tool will set them completely, no need for the "tighten and do it again" you see in so many videos. The long handles give lots of leverage and it doesn't take much effort to completely set nuts with this tool. Highly recommended.
