Put down about 20k staples so far and this thing puts them down no problem with very few jambs and sinks them to the right depth too without blowing through material. Very happy with it.

The stapler broke after a week of use. Then powernail wants me to pay to ship it back for repair. Now I need to buy a new stapler to use while the other one gets fixed. I should note I did not buy on Amazon so unfortunately I didn’t have there great customer support.
