Query: Even better than expected!

I bought this product to build a fence, using composite lumber (very dense, multiple times harder than wood). I used my trusty electrical nailer and it could not penetrate the word planks. Using the brad nailer and the finish nailer, I turned the depth to the middle position, still not sure it would penetrate. Well, it worked beautifully. I could have penetrated two or even three boards with one shot if I wanted (and did two thicknesses often). I built the 55 foot fence with absolutely no problems. Of course, I wanted to nail all day. Set-up was a breeze. I have now bought other tools to use with it. The feedback I read before buying said not to use it for sustained uses (painting), but using a cut saw is not problem at all. For the money, outstanding!
