Review title: Great labor saver, fun to use
Product review: This tool is a great labor saver, fun to use, and well packaged. I am notoriously bad at driving nails by hand, and this tool has prevented untold amounts of bent nails, bruised thumbs, and sore wrists. I don't know how I ever got along without one. My only complaint: I'm not crazy about the screw-in collar that secures the nailing head to the tool body. As shipped, the collar was screwed in so tightly that while trying to remove it, I damaged one of the included wrenches. Once it finally came off, I had no further problems. However, I'm always worrying that I'll overtighten it again, or that I won't tighten it enough, causing it to vibrate loose during use. Porter-Cable should reconsider the design of the collar mechanism; otherwise, great tool.
