I got this nailer to pour 1/2 inch and 3/4 inch through my 30 x 30 foot bedroom and bathroom ceiling and floors. French doors and cupboards. I was amazed at how quickly (in time) all my butt glued moldings came on when it came time to assemble them with this finishing nailer. The nailer left no marks on the cedar moldings other than a tiny pinhole that the primer and paint would cover up. I am very happy with my purchase and would recommend it to others; ) to save your fingers and time on small projects and get this nailer. NOTE: The depth driven up to Brad 18 GA nails is set by your (Psycho settings for this pneumatic nailer).
