easy to lift my cars.cons, it has to be precisely aligned where there is no side load force to try to lean it. for example, as the car rises, it will pull the jack toward the car. this small misalignment can cause the jack to become erratic in lifting or lowering because of the internal telescoping mechanism cant tolerate any side load whatsoever.that means you may have to reposition it a few times to estimate where it needs to be when the car is lifted and begin with a counter lean to compensate or some other block on top etc.
