My sons bought me these HF jack stands a year or so ago, and one of them sent me this defect-related article yesterday morning. I checked my jack stands out, and I do not have any of the referenced part numbers.
Regarding the comment hoping that this jack stand model is not also produced by the same Chinese manufacturer for other companies selling jack stands, I believe that it is safe to assume that it IS manufactured for other companies. These Chinese companies are typically job shops, manufacturing for several sellers, using a common set of machines and tooling.
