Two good names in jacks! Or they were, don't have current knowledge now.My sons and I jointly own a Hein-Werner 3.5 ton floor jack. My experience with the predecessor of this jack was one produced by Walker, and that jack was "idiot proof" to the max...it stood up to decades of teenage use and never failed to work properly and that's saying something. Current manufacturer is Chinese owned but production is in America. We've had this one for three years and no issues, but then again, it is only used occasionally.
One thing, people are going to undoubtedly have some part of their body under the truck when it's raised. Please don't buy a pos, spend money for a safe one.
