This is a great addition to my workshop equipment. It is very easy to transport, setup in position, and inflate at a controlled rate. I have left it inflated holding up my 4WD over a couple of days without loss of air pressure. I am not sure the wheels are in the correct location and may get changed when I have time. Also the handle could be 300mm longer to make it easier to place in the best position without having to get on the ground. I also notice that the hinge at the bottom of the handle has been deleted from my model. A pity as it could be usefull at times. I have even used it to lift my bed up so that I could change the wheels under the bed. All in all, a very usefull tool.
