                    Cordless is the way to go super easy . We use this weekend for home usually not commercial or business.

                    The battery life is great with this. The only downside is the wind-up time compared to other brands.
                    by
                    This nail gun is easy to load and you can adjust the power to get the nail depth you want. I like that I don’t need an air compressor or have to drag an air hose. I wish the depth settings were easier to read; I will probably find a way to add some contrast for better visibility.

                    Terrible shipping and unknown if it works yet
                    Can't review the tool because I'm waiting for it to dry out. It was shipped via FedEx, and they are getting worse by the day. It was delay saying damaged, label unreadable. When it arrived later than normal, the Dewalt box was gone, the bag with the tool in it was inside another box. The bag and the contents were obvious left in the rain, everything is soaked. The manual is so wet, I can't open it or it will tear.

                      The nail gun was simple and easy to use. No hoses, wires or extra equipment to get in the way. I installed new shingles on the 1800 square foot roof of my house with no issues at all. Great tool!

                      Doesn't last long
                      Worked for a couple years now it barely shoots. Considering buying the milwaukee nailer now.

                        No hose is nice!
                        I purchased a couple of these guns to give them a try on a roof job to see how they would do. It didn’t even make it through the whole roof and the nail driver was to the point where it would not retract. Other than that the gun is a little heavier, but it has plenty of power to drive the nails in, I like the not dragging around the air hose but think that the springs inside the nail gun that retractable the nail driver bolt need to be perfected a little better. I returned one of them to Home Depot and they replaced it with a new nail gun, I haven’t use the new one yet, I was hoping that maybe it was just day manufacturing defect on that gun?

                        Jams after a few nails
                        Was exited to buy this to do siding. Would only shoot 2 or 3 nails then it would either stop shooting any , shoot 2 nails at the same time or jam the firing pin all together! I Tried everything! Putting less nails in it (incase it was a feeding problem), tried opening the gun after 2 nails to make sure it was feeding properly ,tried cutting the first wire so it doesn’t hang up And still was not working properly! I picked up a cheaper gun that runs off of a compressor and never jammed!

                          Convenient and powerful but heavy
                          I was very impressed with this nailer. The first thing you’ll notice when you unpack it is that it is a beast. It comes in at 8.2 pounds with the included 2.0ah battery and a coil of 1” roofing nails (by my scale). Loading the nails is pretty easy and you are ready to shoot. On the nose of the nailer is a wheel to control depth of drive. Even when on the lowest setting it embedded the heads into my test stud. I also tried it on a roof mockup of OSB and it worked better (see photo). Battery life was terrific, I shot over 100 nails (1” electro-galvanized) and it still showed full power (3 green bars on battery). Rapid fire was not a problem the nailer, it never hesitated. It is quite heavy. I don’t see it for all day use. But on a small repair job or on that precariously steep roof, working without a hose is very convenient. I’m sure they will continue to get lighter. But this first generation DeWalt roofing nailer is almost a home run. B+
