"Easy to use and do the job well. Use the correct tool as it has a magnet to hold the screw in place. I suggest cleaning away any swarf with a small brush before seating down otherwise the washer may not bed properly. If possible have two batteries or two rechargeable drills as they require a fair bit of power to insert through steel, I was going through about 2mm steel and probably got 25 to 30 screws done before running out of power. Pro tools may do better. Also work well on wood."
