The Good: Looks very smooth and clean. They're very strong and won't strip out.
The Bad: Absolutely nothing.
I have a 24mm bolt in polished. Most stock bolts are at least decent, but these are the best. You'll never have to worry about your fork bolt stripping or breaking ever again if you get one of these. They look simple, clean, smooth, and awesome overall. No awkward or random tools to use it, just a 6mm or 1/4" allen. I would definitely recommend them.
