This air jack does work and it is fast for my needs: a Fiat 500 Pop, a Fiat 500 Abarth and a Nissan Sentra. Both Fiats have lowered suspension and this jack is low enough to get where it needs to go. Having said that, there are no assembly instructions at all. There is a sheet of paper with icons and a short how to use but none for assembly. However, It is not difficult to figure out. You will need a 10mm wrench or socket with an extension and a Phillips head screwdriver to attatch the 6 nuts and bolts for handles and control block (sorry about the oil marks on the instruction sheet, that's from having to use a 6x1.0mm die to fix the thread on one of the bolts!) You will need scissors or cutter and 13mm wrench to attatch the hose on the Control Block as well. The hose supplied is longer than necessary and, in my case, when attatched as is, the hose kinked at one of the bends, shortening the hose removed the kink. My jack was supplied with a 3/8 inch air hose fitting. My compressor and hose uses a 1/4 inch fitting (as do most home DIY). I had to remove the 3/8 inch (male) hose fitting on the control block and install a 1/4 inch fitting.
