DEWALT 5-in-1 Multi-Tacker and Brad Nailer,Power Adjustment Dial,Ergonomic Grip

The staples works as expected, I use mine for vapor barrier, so I staple into wood. I have been the comment where it does not drive into wood, it does if the stapler is firmly held, as with any stapler if the grip is loos, the stabler would kick back. I find in some instances where I cannot get firm pressure, using a hand in the back to press it helps. It is durable, I have bropped mine a few times from the ladder and it has survived heavy use and some abuse.
