Appears to be a quality product in terms of materials and workmanship. I will contact Snappy again if I need a different size countersink. I'm not sure if this is due to my own lack of experience with the tool and if it really should be, but the countersink was too big for the #8 screw head I was turning. When I found that I just didn't have to drill as deep to get a tighter fit, this worked for me, but it detracts from the user experience. In the end it worked for my needs and I would buy it again.
