Hi, if you can buy a 4 ton floor jack for under $100.00 consider it junk from China. Throw it in the trash. A good 4 ton floor jack would go for about $700.00 to $1,000.00 if they still make them. But I think the good ones are history [out of business] since the market was flooded with this Taiwon / Chinese junk.
