A staple product
Very handy stapler. I already had several "milwaukee" batteries and a good charger.
I'm having arthritis problems with both hands. I was happy to see how easy this stapler made an Insulating job when compared to a manual stapler.

Great Tool Very Handy and Comfortable. Great Design
I love this stapler, I volunteer with an organization building homes and so I got this primarily for the days when we do insulation, I have not been able to use this for the insulation yet , but I used this apply a tool liner to a cart I was making, I used the 3/8" staples and it worked like a charm. See the Pictures below, no matter the orientation that you hold the stapler , it will fire just fine. The design is very cool, by the look of it you would expect it to fire an ion plasma blast charge instead of staples, but it performed just well. I used this on OSB, 2x lumber and it worked just fine. There is a dial on the top to change the depth, the position of the indicator can be determined by how red or black it is. As of this writing I forget which is the lowest and the highest, but just know that you do not have to guess where it is at when you are using it. The bump fire works great, just make sure you have the stapler pressed firmly against the work surface to drive it all the way through. I noticed that if you hold the trigger for more than 5 seconds without firing a staple, or having the actuator push in on the tip. The stapler will shut off as a safety feature. To fire another staple simply release the trigger and press it while also pushing the actuator into the work surface.

A great addition to my M12 powered tools
this tool totally replaces the hand operated stapler for us. It uses t50 staples which are available everywhere. Anyone with arthritis or hand strength issues will love it.
