Anyone use a pneumatic jack?

Definitely could see a positive side to this in terms of ease of use and multiple use cases. The down side is more stuff to carry, in an already small space, along with a need to install a small compressor or carry one (If one isn't already present). I've carried an ARB jack base for years and have never needed more than that and the factory jack on the trail.
 
It's big and the bag does not have a lot of travel. And the way the bag leans bothers me for use in rough terrain where I need to control movement. My 2 stage bottle jack does more with less screwing around.
