Hi, I have a Porter Cable 15ga and a Dewalt 18ga. Both have worked extremely well. The only problem I had was when I tried to use some nails that got a bit wet, then dried. The plastic strip that holds the nails became brittle and got sucked up inside and it started to jam. I opened it up and cleaned out the debris. Good as new. I just wish I could get Stainless nails for the 15ga at a better price.
