How Safe are Your Jack Stands???

I got these from Northern tool, after I returned the Harbor Freight recalled ones. I got two pair of 3 ton for cars, and a pair of 6 ton for the diesel trucks. They have a wedge that locks the idea in place, plus a lock bolt. I have lots of confidence in them, they are probably 1000% safer than some of the garbage stands I have used over the years.
(By the way, I never had any problems, or lack of faith in the recall HF).
