I picked one up on Monday. I think the quality is pretty good. For $179 they are good deal, especailly with casters. However, I don't think they attached the top mounting bracket to the jack in the correct location. The arms don't quite reach 90 dgrees when lifted to the full height. Either that, or they need a bit longer jack. I extended the supports that the tunnel running boards sit on by a couple of inches. Otherwise, I found the back of the sled was much lower than the front.
