hein werner and most of the other well known Jacks from years ago are all made by SHINN FU mfg and some of the assembly is done here allowing them to claim made in the USA. (I think they put the stickers on here LOL). Shinn Fu bought the rights to the names and consequently you have junk jacks at a premium price.
FWIW, I bought a Hein Werner jack (that I believe is one of the Shinn Fu ones) about 10 years ago and I haven't had any problems with it yet. I admittedly don't use it daily or anything like that, but so far it has held up to a good bit of abuse. Of course, I've never owned one of the older Hein Werner jacks, so I can't compare.
