HF recalled the 6 tons first then a month or so later the 3 tons. I had a set of the 6 tons. There are youtube videos showing what the issue was. I took mine back & swapped them for a "New & Improved" set from them. The replacements have beefier teeth. I have no issues with them. I'd rather have them from someone who will recall defective product and exchange for good ones rather than a vendor that doesn't issue a recall. Most likely any jackstands you buy will be made in china no matter whos name is on them. The correct way to use them is to get your vehicle on them then grab your car or truck and shake it before getting under it.
