It seems to be made very well. There is a sale on this jack and a pair of stands for 99.99. I haven't used it yet but I don't think I will have any problems. The jack has a safety valve for both overloading the jack and over extending the piston. Raising and lowering the jack is done by rotating the handle either clockwise or counter clockwise. The mechanism is done through a set of gears rather than some type of universal joint. I thought this was a good idea. In the end ,however, I think you will find that you get what you pay for and when I am working under a car I don't want to find out that the $30 jack just failed. Oh, by the way, the jack is constructed from cast metal right down to all four wheels, not some nylon or plastic. It also has ball bearings in the pivot wheels and about a 5 inch cup.
