oh my what a game changer this has to be the best investment i have made in a long time, i have lowered vehicles & most jacks dont fit under my sills, i usually have to drive onto a home made wood ramp to get a jack under the car not any more so simple just push it under the car to the rails & turn the valve to raise it, the only modification i made was to put some split tubing on the handle so it's easier on the hand apart from that i highly recommend this jack.
