Purchased this tool to perform the job of stapling a pre-finished oak floor and all I can say it worked just GREAT. I had one mis-fire but that was totally my fault. With the right pressure from you compressor it will work wonders for you as well. If you are going to us this tool on pre finished flooring make sure you purchase the kit that will keep you floor from being damaged or marring. I purchased it and worked perfectly ...not one scratch. The floor came out beautiful.........
