I got this because I was tired of using my pump jack to lift up my lifted 2013 Ram 2500 diesel (heavy) to rotate tires and other maintenance things. This thing lifts the truck so easily and quick too. Assembly of the jack is eh. Had to trim the tubing because when the handle is laid down to get it under the truck the hose kinks. The handle assembly is shorter than what I expected but it does the job. I might try to extend it later. The bag seems to be of good quality. There is some type of rod in the center of the bag so the whol3 thing does not roll while lifting something but please use jackstands with these. I don't normally on normal jacks but this seems much more unsafe to climb under when inflated.
