I can't say enough that I don't have a line and can attach what I need. As a master instrument builder, I was happy about this wonderful offer. It paid off more than other tools. It's not light, but it's not too heavy or uncomfortable either. I try to "rest" between shots to avoid misfires, but after 100+ shots it still hasn't jammed. Several sizes are equally good for 18g nails and I would recommend this nail gun.
