I bought this nailer a couple of weeks after hurricane Katrina in preparation for the work ahead rebuilding some of my house. I've driven about 4000 nails and it has worked flawlessly. I've framed walls, hung sheathing, nailed decks and rafters. It has set every nail from 2" to 3 1/4" with no problems. I've also nailed some ceiling joist when the wood was too old/hard to nail by hand ... no problems. I have not tried 3 1/2" nails yet but from the performance I've experienced so far, I don't expect those to be a problem. The nailer has double fired on a couple of occasions but I was in tight situations where my arm movement was restricted and I'm sure that was the cause. I've read some really good reviews about Hitachi nailers but if I had it to do over I would buy the Senco FP602 again. I highly recommend this gun.

A great nail gun, doesn't jam, is reliable, once it is adjusted right it is very consistent in nail placement and depth.

I bought one of these nail guns about three years ago and now I am shopping for a replacement. Although I have used Senco nail guns for more than 20 years, my new nail gun will not be a Senco. The owner's manual is generic, covering a wide range of Senco models but not this particular model. When it jammed (and it does jam), I had to phone Senco to find out how to free the jam. Although the older Senco nail guns had an easy system for freeing a jam, this one does not. You have to take the lower part of the gun apart. I cannot get the depth adjustment to work consistently. Sometimes it sets a 16 penny nail correctly and sometimes it does not.
