I have not used extensively but this arrived obviously very thoughtfully and well constructed - quite solid. Assembly was easy and no additional tools are required. I have a lifted Ram 2500 and I always had to use a stack of 2X8s planks to use my conventional jacks. This eliminates that problem...I can go right to the frame and lift away with no issues.
Great jack can reach frame now with 8 1/2 lift
I purchased this not only for my Jeep but for lifting tractors in my gravel lot when needed to work on them. Compared to my old steel caster floor jack this is a dream. No more dragging a jack through gravel and dirt to do work. It has handled everything from my backhoe on down to my compact tractor. Only complaint I would have is the lack of a storage solution for the handle.
