Interesting. Other than the fact they are pretty, I personally think the McGards stand as a good competitor, especially since they are about $50 cheaper.
Do you live in an area where it snows and the roads are salted? Proximity to the ocean?
I live in Southern California near the sea and I've seen friend's open-ended lugs rust to crap within weeks, probably really cheap lug nuts but still rust nonetheless.
Anyone care to chime in?
