I_e been using this for about six months now and I like it a lot the only problem I had is when it showed up the valve for filling it was broken off so I just went to my local hardware store and bought a new ball valve and used an easy out to get the broken piece out of the Air distribution block. It is important for everybody to know that it is intended to lift only one tire at a time if you try to lift the whole front of the car at one time it is not safe but it works very very well for lifting one tire at a time
