Tried this Hitachi nail hammer today. I bought it few days ago. Pretty impressive and relatively light. Feels like quality. I bought several magnetic bracelets and attached nails to one at arm's length. Much better than lugging around a 12kg nail gun. My next door neighbor had a pool inspector come and keep his section of the fence 6ft up and out of the way of kids or drunk neighbors so no one would drown in his pool. Ideal time to practice in a hurry. I bent (2) nails, but after that the learning curve was pretty smooth.
