I need to fix a small area on a rear lug nut. It took a couple of times but the threader allowed the stripped lug to restore to use again. Good for quick refinish but I would not recommend threading an entire lug nut.
Pros
Saved me plenty of $$$ not have had the whole plate of 5 replaced!
Cons
The indexing pins may not align correctly with the threads being repaired, causing inaccuracies
