I figure HF is fine for low tolerance stuff like this. I mean, it's a big piece of steel, how hard can it be right? I don''t buy power tools or anything precision from them but I've bought jacks, stands, a gantry crane (that could be scary if it failed), press, etc and not had any real problems. You go in knowing it's not top quality stuff but in general as long as you're aware of what it is it's fine. I also have one of their 44" cabinets and plan to add another as they seem to be by far the best bang for the buck.
Like I said, I was lowering the truck from the front. It had been sitting on 4 of these stands. The two at the rear would have seen some side loading as the front came down and that combined with having the stand at full extension likely caused the failure. it looks like the weld where the pyramid attaches to the ratchet/collar failed. Done correctly, the weld should have been every bit as strong as the base metal, yet you can see it clearly tore free at the joint.
Will I buy from them again? Probably - what are the alternatives? Pretty much everything else will also be Chinese I'm sure - parts store or hardware store stuff isn't likely to be any better than HF. Sears/Craftsman once upon a time was a good alternative but they've gone to crap in the last 15 years or so as well. Other than that you're looking at spending big money on truck brand stuff assuming you can find it at all.
