It will lift up the vehicle in 5-10 seconds and that is letting in the air slowly. If I would buy another one I would purchase the one with 6 steel pipes. It lifts the same weight and looks the same but the steel pipes inside would make it more sturdy and it will lift 3 inches higher. 18.5 inches where as the one I bought 15.75 inches. it only cost 5 dollars more. I am ordering 2 with the steel pipes for my sons for Christmas.
