I bought the 1500lb ones too to move my wifes 2000 VW bug around the shop. The concrete floor is smooth and I found it difficult to do. The back moved easy but the front was a bear. I put the car back on the ground. I was pushing and pulling so hard I was afraid I was going to mess up a fender. I suppose if you had a couple or 3 people it would be easier. As John said, they don't really store well either. I am trying to think of an alternative use for them now....
