Crazy Not To Have This Gun
I cannot tell you how pleased I have been with this gun, but I will try. I own quite a few nail guns, a lot of Hitachi and some Bostitch, but this is one of my favorites. Although I cannot write about its durability, I can tell you that this gun does a fantastic job fastening wood to concrete. I was skeptical to say the least about how this gun would perform. There are not a lot of concrete nailers out on the market, but those that are, have a lot higher price tag. So I contacted PNI and asked them if this gun would really fire nails into concrete. I was told that they had tested the gun and had good luck with concrete up to 20 years old, beyond that they had some splatting of the concrete.
I decided to purchase the gun, and if it turned out to be garbage I would just take advantage of Amazon's generous return policy. I ordered 2 1/8, 1 3/8, 1 1/4, inch T-nails and promptly went to work on my brother-in-laws 2 year old basement. We were able to quickly attach the bottom plate to the concrete floor and found that the nails held much better than those applied via a ramset, and were way better than the Tapcons we had purchased.
In fact when we cut out the bottom of a door way, we had accidentally misplaced one of the nails in the 2x4 and we had to use a crowbar to pry it out.
The next job required me to apply strips of 1x3 to an old fire place chimmney, the back side of which had been plastered and paneled over in the past. Previous carpenters had a bear of a time working with this wall. I was able to quickly fasten the strips with the 1 3/8 inch T nails and provide a perfect backing for the drywall. I had originally used 2 1/8 inch T-nails, but they didn't always fully sink, and were probably overkill.
Most of the time this gun sinks the nails, on the rare occasion it doesn't, I am probably using the wrong sized nails or am getting sloppy with my procedure. For the most part though, the hardened nails are tough enough, for me to finish driving them in with a regular hammer.
The single trip/bounce trip works well, and I have had no jambs.
The gun also comes with a nice case, containing oil, proper wrenches, and nipple.
I have paid more for staplers and finishing nailers, the speed that this gun affords you, for this price, is way better than ramsets or tapcons. Gun also works nice for attaching lumber without splitting wood, since the T nails are thinner, but stronger.

Good, but not great in old concrete
Using this gun in older concrete (30 year old, in my case) yields mixed results. If I could get the correct size nails, I'd probably fare better. I am attempting to fasten 1 inch thick material to the concrete, and it has some issues. With 1-3/8" nails, it lacks good holding power, but it doesn't have the power to drive a 2-1/8" nail into the concrete. It is penetrating to a depth where a 1-5/8" nail would be fully set, and if the nails were that length, it would work fine. Using it to hang 3/4 inch plywood on the wall with the 1-3/8" nails worked fine, as did hanging 2x4 on the wall with 2-1/8" nails.

So, while not perfect, it still beats using a "hilti gun" (the 22 caliber cartrige type guns) to drive nails in concrete.

Saves time and headaches
I recently installed hardwood flooring in my home. Originally, I placed a 1/2" subfloor and hammered it down w/ standard wood to concrete nails. It took a couple of days and the nails often went it bent and stressed. I also hammered my thumb a few times doing so. I looked into a ramset, but the noise and number of shots needed to keep the subfloor down discouraged me. Well to make a long story short, I had to remove the 1/2" subfloor and use 3/4" instead for my particular application. I ordered this gun and 2 boxes of the 1 3/8" nails. I was able to install the subfloor in about 2 1/2 hours. The nails seem to hold pretty well, but during the installation, I did hear an occasional pop here and there. All in all, this was well worth the money.
