I have looked into this product as a contractor and for a fellow contractor and found that it is more of a DIYer tool than I would use placing hidden fasteners . The clip provides the spacing that goes with the specific decking materials. I still fasten treated, cedar or redwood decking from the top down because the potential cupping when the boards dry out. I have had success in placing the clips into all different decking materials by drilling the screw through the clip into the joist and not placing it into the deck board to keep it from splitting the edge. I use tiger claw most of the time on wood decking and the recommend clip with composite. It is up to each one of us in how we go about fastening down the decking boards.
