I have a bunch of M12 tools. I don't know if I needed this, but it was more of an impulse buy and a nice addition to my collection. First, it uses standard arrow brackets. It's very easy to load, and you can pull the trigger like a standard stapler, or pull the trigger while striking like a percussive action (similar to a nailer). The increase power/sewing depth knob is a little tight, but it's fairly easy to get to grips with. I recommend taking an unused piece of material and playing with the Power/Depth knob until you get the depth you want. That's great. That will probably accompany me for the rest of my life. I'm a big fan of Milwaukee M12 instruments. I don't know how many staples you need, but this tool is way better than a hammer stapler at overhead staples (the main reason I bought this tool). Also, a few thoughts and recommendations - I recently purchased a Milwaukee M12 Right Angle Impact (RAI) driver. This is my favorite M12 tool. It only hits a few places where normal exposure doesn't fit and has amazing power. My least favorite M12 tool is their HackZall saw. I don't know, maybe I'm just using it wrong, but it doesn't cut very well. Even if I fix the workpiece, the saw just jumps. The only use I've found for it is cutting plastic edges, and even that gives the saw a workout.
