This is a nice and robust jack. I wish the base were a little larger, but not a big deal. It does a great job of supporting an already lifted item, but don't plan on using it to actually do the jacking. I bought these with the intent of using them to lift my Delorean to work on it (I had to work that into the review somehow; fun car!!) as I hate the hassle of putting the floor jack under the rear and then getting the jack stands. Unfortunately, these jacks just can't be used to lift the weight, even with an air compressor driving the impact wrench. I don't think it is these specific jacks though, it is the physics of this design. Too much force at the lowest height. Good for the recommended use however. Good price.
