HF took the appropriate action with a much-publicized campaign to inform owners and refunded them for the defective stands.
It would be foolish for them to follow up that effort by putting more defective product on the shelves, and put themselves at risk of the another costly campaign, or liability for damages should someone be injured, so the current stands should be fine.
However, if buying more than one pair, be aware that there are two versions of the 3-ton models, and it also applies to the 6-ton models.
Between the two, the dimensions are slightly different, and one has a thicker post than the other, which will be evident if the store has both versions on display. The shape of the saddle is also different.
With the 3-ton models, the thick post version has a lift range of 11-3/8 x 16-7/8", while the thin post 11-1/4 x 16-7/8", as printed on the box. That is the easiest way to tell, as the same product pictures are used for both.
I'm not aware of the specifics on how to discern the 6-ton models, but it seems they also follow the not unusual HF practice of having different revisions of products in the supply chain, and being mixed in store stock, not just for jack stands.
HF uses both item numbers and UPC codes to discern variations of the same product, but it's not consistently applied by one method or the other.
