The jack I ordered/received was not the pneumatic version shown now. My review link currently goes to this jack only. What I received was the manual 20T jack, which is what I wanted, since I don't usually have air close to where I do much of my work. The pneumatic version would be cool, but I wanted a manual one first. That said, the jack I received is everything that we love and hate about bottle jacks. Super heavy and awkward, goes up slow, only lowers with pressure, but fits in tight spaces and will LIFT like nothing else. I used it for a tire rotation on my truck and it performed as it should. So much lifting power, I could barely tell the difference between raising the jack up to the axle and actually lifting the axle. It seems like a solid jack, but not one I would use regularly for automotive work. At least my truck sits high enough it will fit underneath, so it will come in handy for some things, I'm sure. While I did not choose the pneumatic version, I am jealous of those big return springs it has. The 20T manual jack will not lower with its own weight, it has to be pushed down. But I wanted a plain Jane 20 ton bottle jack and I got one. It performs just as I expected and I have no complaints. If I can keep it out of the weather, I think it will serve me well for years.
