As mentioned, although the idea is a good one, the manufacturer has failed to provide quality control for the components. I tried driving one of the nails into a piece of wood but I couldn't get the tool to sit on the nail because there was a flange of excess metal around the top of the nail that had to be filed first. I was able to get the driver tool to seat properly. Every nail I tried had the same problem. Finally managed to file off the excess metal and get some nails working, but really? If you need to use them for a larger project, good luck - I'd look elsewhere.
