I own a ton of dewalt stuff..Its all I buy.. Ive only had trouble with two things over the yrs. This nailer is one. I just wont work. I have taken this thing all apart and found nothing wrong with it. When I pull the trigger it just hisses air... Stay away
I am a DIYer who's been using this nailer for about a year - it's vusually in good condition but mechanically it has stopped working to quality specs. I am very disappointed. I changed the trigger valve but am still having the same misfiring issue. I love all things dewalt - table saw, two miter saws, drills, circular saw, etc etc but this bailer has really let me down.
