Aye, therein lies the issue. We have no evidence that their jack stands are poor quality materials. I have considerable evidence that their jack stands can be abused and not break or crack. I have bent and otherwise distorted them from severe misuse, doing things that would be expected to bring out the worst in any design, American or American fabricated in China.
Sockets, especially impact sockets, are typically hardened which is a process that to be successful requires proper alloys probably heat treated correctly with proper care. Sockets are actually much higher tech by far than jack stands.
Luckily, lives do not typically depend on a socket because they can and do fail. I don't recall ever personally breaking a socket of any kind, even the cheap Taiwan 1/4 inch drive sets they give away for free for opening a checking account. (Probably Chinese now.)
So where do we stand? I have abused the heck out of HF jack stands and they have never cracked or broken. You have broken HF sockets. How applicable is breaking sockets which are hardened and much more prone to breaking in predicting the likelihood of a soft metal jack stand to fail catastrophically?
I don't like to live on the edge or take big chances with my life nor recommend such actions to others. Quite the contrary, I am usually the guy being laughed at for taking strong pro safety stances. I'm the guy being accused of being a girlie man or a "hand wringer" because I take a stand in favor of safe practices.
In this instance I just don't see the applicability of judging a jack stand by your socket experience. The technology and metallurgy are so dissimilar as to prevent experience in one being a good predictor of experience in the other . They are not strongly correlated.
Stated more simply, the lower tech the item the less chance HF manufacturing sources will have screwed it up. You don't get a lot lower tech than a jack stand.
Now, don't get me wrong. I'm not trying to convince you to use a HF jack stand but I would like to hear why you think your experience with sockets is a good predictor of jack stand performance/safety and would be more valuable than hands on experience in "destructive testing" of HF jack stands.
