Rated 4 out of 5 by from Nice Nailer At A fair Price I received the duo fast nailer recently. It came well packed in a heavy cardboard box, which also included a pair of safety goggles. It does not come with an air fitting. It comes with the trigger set up as single nailing, to change to bump nail mode all you have to do is pull the o-ring off the trigger pin, push the trigger forward and push the trigger pin back thru and slip the o-ring back on. Just be careful not to lose the o-ring its very small. The trigger has imprints on it so you know it's in the right place. Depth of drive adjustment is easy as all you do is turn the adjustment screw on the nailer head, The unit also comes included with a nice rafter hook and holds two full strips of nails. The gun fires smooth without stutter or bouneback and drives the nails in well. It's a little heavier than some of my other guns, but not enough to make a difference to me. Overall I think it's a good quality gun built well and solid at a fair price.

Rated 5 out of 5 by from I should have bought this a long time ago This thing really drives the nails. Fast and as deep as you want. Never had a miss fire and holds a lot of nails. This is the best nailer I have owned and a real treat to use.

Rated 5 out of 5 by from Not too heavy and gets the job done fast! Using this nailer to install new sub floors and build steps to our place. Sure makes the job a lot easier having this nailer It was easy to use right out of the box. Lightweight enough for me to handle without my arms getting tired. It might be more than we need for our small job but it has been really nice and making short time of the nailing process. Haven't played with the adjustments, but it all looks easy and self explanatory . Feels very sturdy and strong and good for heavy use on the job.

Rated 5 out of 5 by from High Quality Framing Nailer This is a very finely crafted framing nailer. The gun is very powerful, capable of burying the head of a 2 1/2" nail deep into stacked 2x4s. The fit and finish are superb. Most of the gun is metal and the handle grip is comfortable. Nails slide with ease in the magazine, and the feed mechanism glides very smoothly in both directions. The gun feels very solid in-hand, and the controls are large, easy to see and access. This is a nice tool.
