I've only used this nail gun for a few small jobs and I'm already impressed. I don't have much experience with other brands of nailers but this one just works every time and I'm very happy with it. nails and ran some tests with hard maple. I shot a 3/4 inch diameter piece of hard white maple into another piece - it's HARD maple. Each nail is set perfectly and the holding power is amazing. I'm still amazed how such a small thin nail can penetrate such hard wood and not bend. Plus, it runs so quietly that you won't know if it actually did anything until you check for yourself and make sure the pen is really there. I don't think I'll ever use my 18 gauge nail gun to install a crown molding again. For most jobs with this gun, you don't even need to caulk the holes. They are so small that you cannot see them unless you are a few inches away. Greks foresaw almost everything when designing this weapon. It includes a belt clip, an Allen key for clearing paper jams (which has never happened to me) and proper protection! I can't stand that most other nailers have guards in the way that prevent you from getting your gun into tight corners. It's the only thing I would appreciate if they added some pins with the gun. However, I ordered a few packs with a gun. This little guy accompanies me to every job I go to. This is my new best friend.
