I don't impress my friends with this
40 piece SAE tap & die set but it I've had it for more than 15 years and it still does the jobs on my 3rd/4th restorations. I bought a higher quality tap handle but it broke. I just keep using the cheap handle that came in the kit.
I have not had to find out if they honor the life time warranty.
What type of work do you intend to put these tools to?
I do not know about comparing these to a Yugo, but maybe a comparison to a Geely or a Lifan might make you feel better?
