Review on Optimized Centering for Snappy Hinge Bits by Samuel Nguyen

What I love most about this product is that it's made in the USA! Over the years I have purchased three sets of HD and HF pan attachments. They worked fine for a while, eventually failed, the bit or spring broke so the case didn't retract as intended, or the accuracy seemed different. When this happened recently I went shopping and was dismayed to find nothing made in the USA. Lowes, HF, HD and ACE mainly sell Chinese-made instruments, the quality is so-so. Gone are the days of quality tools that last a lifetime and that you pass on to your grannies. I was thrilled when I came across these USA made snappy swivel bits with interchangeable drill bits. With high quality expectations, I therefore give them a 5-star rating across the board. I'll be trying them out on closet doors soon, so there will be a "edit" soon.
