I used this tool on my first DIY prefinished hardwood flooring job. My compressor regulator was set at ninety pounds and with B & C Eagle ABCS1516 2-Inch Hardwood Flooring Staples, using it was a breeze. Pulls the boards in tight and flat to the floor and didn't damage the tongues. Never had a jam, although if you don't have it seated and firmly planted on the floor, you may get a staple that doesn't go all the way through. Used a Dremel to cut the staple and then restapled. With 3&1/4 boards, only had to face nail one row against the wall. Smaller than that I'd say you may have to do two rows. All in all, I would definitely buy and use this tool again.
